Rear suspension arms and mounting

[Jackstevens98]

Has come up on advisory that my rear upper suspension arms both sides and mountings are corroded but not excessive. Two questions is this something that I could easily fix myself before they get too bad. If not how much would a garage charge parts and labour to replace these

The parts for both sides will cost circa £250, and they are secured with three bolts, if fitted with a rear anti roll bar, two if not

Unfortunately in each case, I've encountered, the outboard bolt has been seized solid, it is possible with a bit of patience to work these bolts free, however the rose joint bush will require replacement more likely as not.

So back to your question, I suppose the best course of action would be to jack up the car, place it on stands, remove the back wheels and take a good look at the arms, wire brush the loose crusty stuff off, wash any salt deposits from corrosion cells, and treat with waxoil or similar.

Remember though, what may at first sight appear to be relatively minor.........

Ive recently replaced both mine along with the rose joint bushes. Quite a straightforward job if you are patient, only problem I had was one of the outer bush bolts was seized solid so, as I was replacing the bushes, I had to use a grinder and cutting disc to aid removal

Mine looked fine from underneath but, like Brian said, jack up, take wheels off and have a good rummage.........I was quite surprised with what I found



Take the advice of those who know on here and you will be fine doing it yourself.
Oh yes, ONLY use good quality hex sockets, NOT the bi-hex ones and plenty of PlusGas

the arms shown in the pictures already posted are about £120 each.

easy to do if, bolt in centre of car not seized nor the one by the axle. do check your suspension springs at the same time as I found one of mine had snapped.

there is info and a how to (i think) on the forum about changing these and also what tools you need.
these are something you can change if you have the right tools and I advise having a torque wrench for doing the bolts back up

It does look a daunting job but once you get started its not that bad, I soaked all of the bolts especially the "hidden" one for a few days before trying to remove them, to my surprise they all came out without problem.

Unless your car has never been in the wet, or salted roads, the chances are they need changing.
I've done two sets, both without the seized bolts and consequent issues noted by others, but that's no guarantee you won't have these issues.
I wouldn't class the job as a simple diy job, sure it doesn't take long, but you are working under a heavy car, with compressed spings, potentially seized fixings, and some of them (the pivot pin) need a specific length socket to remove it.
So, if you have a comprehensive tool set, axle stands, time and experience then its do able, otherwise look for an honest garage or one of the traders on here?

Mine went from solid enough for a wire brush and squeeze, to cracked , a one finger hole and a crack below flaked paint/ underseal in the space of 10 / 11 months. So I would believe it could happen.

I accept we have no option but to pay the asking price but it would be interesting to find out how much the items cost to purchase wholesale and where from (not taking anything from the traders here because as you say there's warranty claims etc to take into consideration
However It's the £119 that interests me though it just seems strange that the suppliers I have checked all want the same money.
As mentioned in my previous post a lot of people would just scrap the car as the arms are expensive if you consider what some members have paid for their cars and it has to be remembered not everyone can afford £238 plus the cost of fitting

Totally agree Steve, however, it seems that mainly it is an x part group item, and being part of a group, there can be no competition between them (my opinion) . the price they are now will be less than any dealer would've been, they certainly are cheaper than they were 2 years ago when I bought mine.

As far as those that can't afford to repair, without sounding harsh, then the car is not for them. That argument can be applied to any car, and it again without meaning to be harsh, will come down to living within ones means. At £119, I would be surprised there would be more than 15 to 20 profit.

Just been reading a post on here regarding the quality of some of the x part arms
The problem seems to be the tightness of the bush fitted to subframe side of the arm
This was apparently a set of arms sourced from India
