Suspension is the fail that surprises people. It rarely makes a noise you would notice on a loaded van, it rarely lights a warning lamp, and it is the largest single group of defects the DVSA records on cars and vans. This guide is written for van owners and small fleets first, because vans carry weight every day and wear suspension faster, but every figure for cars and light vans in classes 3 and 4 is here too. In summary:
The DVSA publishes initial failure figures by defect category for every MOT class. The table below is the full 2025 to 2026 year, published on 10 September 2026, which is the most recent complete year. "Percent of tests" is how many tests had at least one defect in that category. "Percent of defects" is that category's share of every defect written down.
| Category, 2025 to 2026 full year | Class 3 and 4: cars and small vans | Class 7: vans 3,000kg to 3,500kg |
|---|---|---|
| Suspension, percent of tests | 8.90 percent | 8.43 percent |
| Suspension, percent of all defects | 20.49 percent | 13.73 percent |
| Suspension, share of Dangerous defects | 5.32 percent | 7.08 percent |
| Lamps, percent of all defects | 24.89 percent | 30.58 percent |
| Brakes, percent of all defects | 15.18 percent | 22.38 percent |
| Overall initial failure rate | 27.51 percent | 34.00 percent |
| Tests in the year | 33,310,534 | 1,107,819 |
Two things stand out. On cars and small vans, suspension is the biggest category there is, bigger than lamps once you look at share of defects rather than share of tests. On heavy vans the order changes: brakes and lamps come first, suspension third. That does not mean van suspension is better. It means heavy vans fail more of everything, 3.09 defects per failed test against 2.39 for cars, and brakes take a bigger share of a bigger total.
The Dangerous column is the reassuring one. Suspension is a small share of Dangerous defects on both classes. Tyres and brakes are nine in ten of every Dangerous line. Most suspension fails are Major, which means the vehicle failed but you can legally drive it to be repaired if the MOT has not already run out.
Section 5.3 of the DVSA inspection manual for cars and light commercial vehicles, updated 1 June 2026, covers springs, shock absorbers, arms and sub-frames, joints and bushes, air suspension, and the structure around every mounting. The tester jacks the vehicle so the springs are unloaded, then levers and rocks each wheel looking for play. On the front of most vans this is done with wheel play detectors, the plates that shake the wheel while the tester watches the joints.
The manual has fixed limits that garages rarely quote. Play in a spring pin or bush is excessive above 2mm on a 12mm pin, above 3mm on a 25mm pin, and above 10 percent of the diameter on anything bigger. A rubber bush is only rejected when the tester can see serious deterioration of the bonding or the rubber, not because it moves. Many bushes are designed to move. A MacPherson strut top mount is allowed to have lateral play when the suspension is hanging; it fails only when the play is wear.
Shock absorbers have one rule that saves money: slight seepage leaving a film of fluid on the body is not a fail. Severe leakage, negligible damping, or a worn bush is. A missing bump stop rubber is not a fail at all, whatever a garage tells you. And the tester is not allowed to fail a shock absorber for being missing unless one was fitted as standard.
The structural rule matters most on older vans. Any load bearing metal within 30cm of a spring, sub-frame or suspension mounting is a prescribed area. Corrosion there that significantly reduces strength is a Major fail, and if it is bad enough to affect control it is Dangerous. This is where a nine year old van that lives on gritted roads fails, and it is the one suspension line that can cost more than the van is worth.
The prices below are for an independent garage, parts and labour, from the sources named under each. Vans sit at the top of every range and often above it, because the parts are heavier and the job takes longer. Coil springs and shock absorbers are replaced in pairs across an axle.
| Manual reference | What the fail sheet says | Category | Usual repair | Rough cost, 2026 |
|---|---|---|---|---|
| 5.3.1 (b)(i) | Spring or spring component fractured or seriously weakened | Major | Pair of coil springs, one axle | Front £175 to £275, rear £167 to £177 on a car (Checkatrade, table updated May 2024, page June 2025). A Transit rear leaf spring is £540 for the genuine part alone on Ford's own parts shop, before fitting. |
| 5.3.1 (b)(ii) | Spring main leaf fractured | Dangerous | Leaf spring, one side or both | As above. Cannot be driven away. |
| 5.3.2 (b) | Shock absorber severely leaking or not functioning | Major | Pair of shock absorbers, one axle | £150 to £500, average £379; front pair £416, rear pair £321 (Bumper, October 2025). Transit Custom front £240 to £455, full size Transit front £247 to £633 (Fixter, September 2026). |
| 5.3.2 (c) | Shock absorber bush excessively worn | Major | Bush, or the whole unit if the bush is not sold separately | £60 to £120 labour an axle plus the part (Bumper labour figure). |
| 5.3.3 (b)(i) | Suspension component excessively damaged or corroded | Major | Wishbone or arm, one side | Varies widely. A pressed steel wishbone with its bushes and ball joint is often £150 to £300 fitted on a car; van arms are more. |
| 5.3.4 (a)(i) | Suspension pin, bush, joint or bearing excessively worn | Major | Ball joint, drop link, or bush | Ball joint £75 to £180, average £90 (Bumper, July 2025); Transit lower ball joint £155 to £311 (Fixter). Anti-roll bar drop links £60 to £130 a pair (Bumper, April 2026). Anti-roll bar bushes around £80 to £180. |
| 5.3.4 (b)(i) | Suspension joint dust cover severely deteriorated | Minor | Nothing, or a new boot | A Minor is a pass. Under £50 if you replace the boot. |
| 5.3.4 (b)(ii) | Dust cover missing or no longer keeps dirt out | Major | Usually the whole joint | As a ball joint. |
| 5.3.6 (a)(i) | Load bearing structure within 30cm of a mounting significantly reduced by corrosion | Major | Welded repair to the prescribed area | No published range. Small local repairs start around £150 to £300; a corroded rear spring hanger or sub-frame mount on a van can run past £1,000. |
Some of these lines are cheap to argue with. A dust cover that is split but still keeping dirt out is a Minor and the vehicle passes. A shock absorber with a film of oil on it passes. If a garage quotes you for either as an MOT repair, the manual is on your side.
Two are not worth arguing with. A fractured coil spring is a Major fail on the day, and springs snap in cold weather and potholes without warning, so the second spring on the same axle is the same age and usually goes next. Replace the pair. And a corroded prescribed area needs a welder, not a wire brush, because the tester will look for the repair next year and the manual says an inadequate repair is the same Major fail.
GOV.UK's retest page lists the items you can have retested free the next working day after taking the vehicle away. It covers lamps, mirrors, wipers, seat belts, wheels and tyres, and a few dozen other quick fixes. Springs, shock absorbers, bushes, ball joints and structure are not on it.
So a suspension fail leaves two routes. Leave the van at the test centre for the repair and it gets a partial retest within ten working days for no fee. Take it away to your own garage and bring it back within ten working days and the test centre can charge a partial retest fee. Take longer than ten working days and it is a full test at the full price, up to £54.85 for a car or £58.60 for a class 7 van. Full details are in our guide to the MOT fee and when the retest is free.
The practical answer for a working van is to book the MOT with a garage that can do suspension work on site. A spring or a ball joint is a same day job almost anywhere. Leaving it there costs you a day of the van. Taking it away costs you a day plus a fee.
Every advisory and fail is in the free record when you check a registration on MOT Check UK, and suspension lines are the most useful ones for a van buyer because they show how the van was used and how it was looked after.
A suspension fail followed by a pass on the same day or the next is nothing. It is the normal life of a van. A spring or a shock absorber wore out, the garage fitted a new one, the record shows both events. Ask which side and check the invoice if you want, but do not walk away from it.
Look instead at repeated advisories. "Nearside rear coil spring corroded" as an advisory three years in a row means the owner read the advisory and drove on. That spring is now a fail waiting to happen and the offside one is the same age. "Front suspension arm pin or bush slightly worn" repeated year after year is the same story. Price the repair from the table above and take it off the offer.
Look hardest at anything that mentions corrosion near a mounting, "prescribed area", or "spring hanger". On a van past eight years old these are the lines that turn into a welding bill. If the record shows a fail for corrosion in a prescribed area and a pass a week later, ask to see the underside. A proper repair is plated and painted. A quick one is underseal over the hole.
Finally, put the suspension lines next to the mileage. A van doing 30,000 miles a year with one spring in five years has been serviced. A van doing 8,000 miles a year with shock absorbers, drop links, ball joints and two springs in three years has either been loaded past its plate or driven on farm tracks. Our guide to reading a used van's MOT trail covers the mileage side, and the buy scorecard counts a repeated advisory against the vehicle automatically.
Everything in the manual section above applies to cars, which are tested in the same class 4 as small vans. The difference is money. Car springs and shock absorbers sit at the bottom of every range in the table, and a car ball joint is a £90 job where a Transit's is £155 or more. If you are pricing the same advisory on a Fiesta and on a Transit, do not use the same number.
Motorcycles have their own manual and their own data. In the class 1 and 2 figures for the same year, suspension is a small category and lamps dominate. A leaking fork seal is the usual bike suspension fail and the rules for it are in our motorcycle MOT guide.
Suspension is the fail you should expect on any van past its fifth birthday, and on most cars past their eighth. It is common, it is nearly always Major rather than Dangerous, and the common repairs are £150 to £450 an axle. Do not panic over one fail line in a record and do not pay a garage to fix a seeping damper or a split dust cover that the manual says is a pass.
What should change your offer on a used van is a pattern: the same advisory repeated, or any corrosion near a mounting. Those are the lines that turn into a four figure bill, and a seller who left them for three years has told you how the rest of the van was treated. The record is free, so read it before you drive to see the van.
