Full Version: 405 estate rear suspension collapsed

Hi. As above, on way back home with caravan on the m6, massive bang and back left of car dipped down a lot. No noises or anything so it's on the stops. Still on hard shoulder so not had chance to look properly but it definitely is collapsed suspension. I'm assuming it's new back axle. What can I take out from? I've got a saloon sat at home as my spares bin, will that be the same or will it have to be from an estate? If so, what am I looking at cost wise? Is it a DIY job? I've done a normal rear axle on a mk6 escort before, but nothing with torsion bars.

Any advise greatly appreciated. Thanks
It's easy enough to change mate 6 bolts in boot handbrake cables and brake pipes

Axle should be same just different torsion bars/arb
Is it not all one unit then?
Would like to know whats happened there. Broke a torsion bar maybe? Or the splines in the trailing arm have shit it... Hmm.
Pics?

Not sure yet. All I know is there was a bang and now the back left of the car is sat on its arse. I'll know more once recovery has got me home and I can jack it up and have a look. Car has done 170k. I got it at 160k without a Towbar so I know it's not towed before, but the boot is clearly "well used". I've done a lot of towing myself which won't help, but the car was only £300 with full test so I'm not complaining

Not sure what use it is but.....

I'm not taking a picture of the other side, but that's about half normal ride height
Long day for you then sir. Yeah you can see somethings fooked there lol, be interesting to see what you find...
Yeah I'll go with interesting. Opportunity to learn about this type of set up. Luckily just bought wife her first car so I'm not stranded at least
Right, didn't get back till gone 2200 last night, so not had chance to look. Anyway, I'm planning for worst case scenario/easiest solution, any certainty on whether or not I can just take the whole assembly from the saloon? Had a read of Haynes, seems simple enough job, and it doesn't specify estate / saloon for the instructions so I'm hoping for the best....
Just spoke to Peugeot, (they were actually helpful!) They've said apart from 4x4 models and models built for Japan, the only difference that's specific to estate/saloon is updated shock absorbers which seem fine, everything else should swap over no problem. So, work starts tonight....
Good luck mate Smile
Starting work on it tonight. Any pointers would be appreciated as not done this sort of axle before. What I know is remove rear and middle section of exhaust, lower but don't remove fuel tank (which will be fun as it's half full) disconnect handbrake cable and brake lines, then remove (6?) bolts fixing the whole assembly to the car.
No need to touch tank.

Undo the clamp that holds the mid section to the down pipe but I think yours is once peice turbo back

You can get away with taking the backbox off taking exhaust off all hangers and lay it on floor

Coat the brake lines in wd40 and don't round them off

6 bolts and it comes off once handbrake cables and brake lines are off

If you still get stuck give me a ring
there are no bolts in the boot for these, they are all underneath, make sure you clean the torx bolts thoroughly if you try to undo them.

on the front mountings there's two Torx bolts holding the long stud to the body, I would try to undo these rather than the big nut as the stud usually gets seized inside the bush.

on the rear mountings you have two 13mm bolts holding the bush to the beam, or one torx bolt for which you need something like a 120mm long T50 torx bit to remove the bolt holding the bush to the chassis.

best bet for a replacement beam is a partner or a berlingo beam, however they will need some lowering before they go on, my brother's 405 went up about 90mm when we fitted a van beam to his GLD!

Progress. Both cars on stands (point to remember is 2 cars need 4 stands!) Exhaust removed, fuel tanks drained (slow) fuel filler pipes removed. Now too dark to carry on. Got 2 hours done. Time lost to actually moving donor car, then finding 2 more stands, and draining tanks took about 20 minutes per car. 20 litres in seconds, last litre very slow. Should've done that before jacking them up!

Continue tomorrow after work. Hope to get cables / pipes disconnected and get both axle assemblies dropped.

Welshpug, the donor axle assembly is coming from my old 405 saloon so should be set up fine
