Rear Shock Absorber Replacement

Hi,

Looking to renew my rear shock absorbers as the front have recently failed so figure at 85k and 8 years old the rears will be far from at their best and not far from requiring replacement themselves.

I'm planning on replacing the rear shocks myself and was wondering whether there are any other parts such as mounts etc that should be replaced at the same time?

Thanks,

Russ

If you're doing the lot then I would definitely recommend you do all of the mounts as well as the labour should be the same, you don't want to fit the suspension only to find your mounts are knackered and have to go back to it! I have done literally just this myself within the last few weeks.

I used this as a quick way of finding all the part numbers, shame I couldn't find such a kit in the Uk - https://www.turnermotorsport.com/p-1...3-non-m-or-xi/

Ordered all the mounts etc from Autodoc and got a suspension kit from Demon Tweaks, see here for the suspension kit I used, with pics. https://www.e90post.com/forums/showthread.php?t=1469432

Hope that helps.

You absolutely should replace all components associated with the shock. You could probably reuse the rubber hat, everything else needs replacement.

Perfect, thank you for your reply. I completely agree about the mounts. I'll get them ordered along with the shocks, for the minimal extra outlay it woukd be foolish not to order them.

I naively decided to not to replace the mounts when upgrading my suspension. 2 years later the front top mounts were clunking and I had to do the job again which was a pita.

The rear shocks are very easy by comparison.

I was going to say don't get a mechanic to do your rear shocks. You can do them yourself with basic tools. Will take you about an hour.

how easy is it? Do i need spring compressors or anything? Mine just failed an MoT on a leaky rear shock so will look at replacing both but if i can save some hassle and cost I may have a go. I'm used to doing brakes and happy generally getting down and dirty (usually on motorbikes)

Rear shock are easy to change, slightly harder on a touring due to more internal body trim needing to be removed but still easy. In fact the most difficult thing about the job is removing the internal trim. Other than that its just one nut at the top and one nut at the bottom then that shock can be pulled out. Simples.

One thing I haven't seen mentioned above is replacing the bump stops, these degrade over time too and are an integral part of the shock system and so should be replaced with the mounts.

Really easy to be fair - interior trims need to come out, one nut in the top of the shock, and another in the bottom.
If your mounts are starting to look tired, replace them - they're normally held together by a few bolts.

Absolutely a p1ss easy job to do - if you were close to Crewe, i'd offer to help.

Cheers @abeardo, I'm very close to crewe, between Nantwich and crewe these days. I've booked it in for Simon at SC Autos to do as even though it sounds easy enough, I'm on call for the next two weeks so sods law would mean that I'd have the car in bits then need to dash out to work

I'm guessing Eurocar parts are the place to get the replacements?

I got mine on Amazon, as they were cheaper. I got Bilstein B4 (Msport spec). I got them next day through prime delivery too. Shop around ECP aren't always the best.
