Hi hoping someone can help.
peugeot 508 estate 2.0 2012
I need to replace a few components of the rear suspension. Left hand side.
Rear longitudinal bar and suspension arm pictured as parts 2 and 3 in attached diagram.
is it as simple as it seems a few bolts? Any special tools/set up required after?
(I will get the tracking done)
Thanks
Lester

Its as easy as it looks, the bolts are Hex/Spline I think so make sure you have the sockets for them. Item 8 is the toe setting, so if not touching it you should be ok.

That’s great.
Am I right in thinking the bolts should be torqued with the hub at the usual ride height ?
(was going to measure distance while car is on ground and jack the hub to same distance and then tighten ?)

They might be one time use bolts. I would check with the parts dept at your local friendly dealer. :) good luck with the repair.

Is it because they are stretch bolts or just that they are coated with tread lock. If thread lock they can be reused with a dab of new thread lock.

This is what it states
ESSENTIAL : The "Low Friction" bolts (2), (4) are for use only once and must always be replaced. All re-use is prohibited (risk of breakage). The bolts that are removed must be thrown away.

I only changed the rear toe arms as I wanted alignment done and apparently they are prone to breaking they were very rusty, didn't replace bolts but i will get some

Stretch bolts from the sound of it then.

Thanks for reply. Ordered some bolts (10 day wait from France)
Do you happen to know torque setting for the 4 bolts ?

After some more help again….. changed some parts above so went to get 4 wheel alignment done as it’s massively out and the guy was reluctant to adjust the rear as bolt was rusty and looked like it would snap. He had a quick go at losing it and decided he wouldn’t do it. so my question how easy is it to replace the rear toe adjustment arm. Number 8 in the diagram. Can someone copy the procedure is it at simple bolt in/out job. Torque settings would be helpful too. Thanks a lot.

This is the part i changed on mine as they would not adjust as they may break. Get 2 new ones adjust the length if required to match those taken off, refit then get alignment done. I will look up torque

Many thanks. 1 last thing I promise.
Was considering changing the stabiliser bushes on rear anti roll bar ? Is this simple enough. I assume if take the drop links off I can slide it over (it doesn’t split in half like some) so might be a bit more of pain. Once I’ve done this I will have pretty much changed every bit of rear suspension (apart from springs)
Thanks

The rear bushes are attached to the bar and come as one, its expensive as I actually have one waiting for me to fit along with new drop links.

The ones on the bar now are bonded to it hence replacement bar but certainly worth a try, I will take a pic of my new one so you can have a look
