Daughters car had an advisory at MOT re the rear arm bushes, doing around 2k miles a month I think it might become a fail this year, is it better to replace the whole arm or spend time changing bushes? I have also been told the rear alignment will need done too when either job is done, suggestions guys. TA.

All down to cost and time. Will be cheaper to just buy the bushes - but then you need to spend more time fitting them vs fitting new entire arms. How much do you value your own time! Do you have the tools to press bushes in?

How much do you trust the MOT garage? Bushes can be hard to test - they normally just use a big bar and lever it in there - which is NOT ideal as some bushes have voids and more deflection in certain directions. Can't be bad otherwise they would have failed it.

Yes, when you disturb any suspension components you should get a full vehicle alignment - not just one axle!

You might have to cut the bolts out to get the arms off so definitely find the correct bolts and buy them before you do it. I’ve done afew of these it you might get lucky and they come undone.

Are some sellers on eBay doing full arm kits, including new alignment bolts.

If the alignment bolts are seized in it's quicker and easier to drop the subframe and cut them all out that way, access is loads better.
Subframe removal is pretty quick and straightforward.

Sorry to hijack but info on rear subframe seems to be hard to come by.

I'm going to be doing this job at the weekend, I've bought a full set of replacements for the back (Seat call the parts different names) but to me iv'e got rear drop links, wishbones, upper and lower control arms, trailing arms and all new bolts. Access is a pig so i intended to drop the subframe as its just 4 bolts plus the trailing arm recessed ones. My STUPID question is...I'm gonna have to disconnect the exhaust too aren't i?

My bushes are destroyed and won't come out so i have a recipricating saw and 10 new metal cutting blades.
