Rear shock(s) bent?
When going over rough roads the rear of the car is very crashy? and stiff, had the car on the ramps before and jacking it up the wheels go on full droop but, if I stand in the boot the deflection is very slight(even if I get herself to stand on the bootlid too), could they (or one) had got a wee bend on a heavy landing? Any suggestions on how to check without removing them to ensure they compress fully? Ta. |
My rear shocks had similar symptoms when they were leaking badly. Check the damper for misting/oily residue. If it’s a crashing/rattle then possibly a broken spring. Both are easy to diagnose with the wheel off. |
Had the car up on a ramp at work and checked bushes, links etc, also also lifted the car whilst on the ramp using the lifting beam, no broken springs or leaking shocks or change in normal ride height(assisted by one of the MOT testers), the noise etc seems to be when the suspension is in compression hence me thinking there is a bend in something or a partial seizure? |
I replaced my rears as it was banging on passenger side ...turned out rear drivers was seized .
fitted the koni oranges and all good now. |
May have to bite the bullet and remove them to check. Ta. |
If I put the car on a 2 post lift and put a gearbox jack under the rear wheel and pump, that should prove the shocker is free or jamming, yes? |
Bad practice !!
May fall off ramp, trolley jack under tyre maybe better idea at low height |
Ok just a thought, I suppose removing the bottom bolt from the shock and then the shock lifted with a pry bar or similar might do the same. |
Removing a rear coilover is probably the easiest job on the s2000.
- Anti roll bar drop link disconnect - remove shock absorber to arm bolt - remove nuts on strut mount in the boot The coilover by the fuel filler is abit more of a pain but it can be undone via the 3 x 8mm nuts, 10mm bolt and then pull it out of the way. Once its off you can then dismantle the coilover with a spring compressor and test the shock along its full travel. Normally its quite obvious when they are knackered. I think on my car the OEM shocks were okay on compression but on rebound they struggled to push back out. |
Fitted a pair of Bilstein orange to the rear this evening, 45 minutes from lift up to lift down(although I had already removed the boot trim) big difference now, a little more movement but no crashing and banging over the bumps. Bought them from Demon Tweeks, £132 inc vat delivered(next day).
Strange though, the old units don’t seem to have any problems, hey ho. |
You don't need much oil loss for a shock to start doing all sorts of weird stuff.

I suppose so, wondered if the valve units had seized inside but never mind, should maybe be a bit better in the wet with a bit of give in the rear now, will be careful of blind crest though, no more directions from air traffic control after a yump.
On a 2 post lift I didn't bother releasing the ARB links just a little lever down to release/install the shocks, thanks to all who offered advice. |
Possible but not usual without oil loss and severe overheating.
