Rear Handling

[supersticky]

Hi all, seems unsteady at the rear like a wobble if going over bumps dips, at any speed. Took pics seems like nsr tyre is further out. Nothing looks straight.
Any ideas. Many thanks

Time for new rear beam bushes I reckon.

Cheers bud, it originally happened when I went over a slightly raised bridge came off the other side and the rear all of a sudden weaved!

Thai, sorry to hijack you here but do you think dead rear beam bushes could cause my issue with one rear side not raising on the coilover?

Currently stands it’s at max adjustment and only moved 5-10mm. Other side is fine and swapped shocks side to side to rule out a faulty damper.

I never got to the bottom of it other than suspecting a bent beam...

I would say so too

I've noticed some sway recently - first I put it down to bad tyres but I changed those and still get it. I tend to notice it more in the rain but the ride does feel a bit more clunky at the moment.

Normally it happens when I go over poor road surfaces and standing water. If I wasn't as confident correcting this as I am, I think it'd be easy to lose control of the car.

Could it be the same problem?

Yes it could well be I had that and one bush had worn completely and the other side was not that far away

Car's getting on a bit and now I've looked into what I'd actually be changing, it does make me feel like that's what it could be. Looks like it can be a bit of a ballache though? I've watched a couple of videos on YouTube that claim it's easy, but that's on non-VAG cars. Have you done it yourself? I'd probably be aiming to replace the bush rather than fit a whole new beam.

I did do it my self with the axel still on the car
A hammer and a big flat head screwdriver and a small flat head screwdriver and I also knocked out the alloy middle part so I could brake the outer part a bit easier to make the bush a bit smaller so it would be easier to knock out off the axel

Thanks for this - it looks like it's pretty doable without taking everything off, and the last thing I want to do is start taking off brake lines.

The bush is 69mm, I'm thinking? What did you go for? It looks like Powerflex are around £70 but I've heard they can be too firm?

We sure it's my bushes as the car was mint I went over a bumpy bridge at speed with passengers and all of a sudden it sort of fishtailed been like it ever since

Seems pretty likely bushes but surely worth getting it up in the air and going underneath first to check for play with a crowbar. Then check the wheels haven't got any play side to side and top to bottom incase it's bearings or something.

I went with these and can’t fault them but did take a bit to put in had to use a bush tool to get them in even with a good amount off grease on the bush and in the axel but with the tool they soon was fitted
I think the whole job took me about a hour todo

Holy crap - they're enormous. I don't know what I was expecting, but they are bigger!

Any issues getting them in? I'm thinking about making a home made press but I've heard of some people being able to slide them in with a little lube and some gentle words of persuasion.

I think I definitely need them - had more than a little rear wheel steering on the way home today, which I don't remember coming as standard on the Leon.

I used a lot off grease on them and clean the axel up well and used grease in there too plus had to use a tool to get them in took a bit to get them started but went in easy once started

I used one of these bush pressing tools on the most recent pair i fitted but have done loads over the years without and used to improvise with various metal plates, nuts washers and threaded stud.
The inside of the rear beam needs to be spotless and its worth whizzing around it with a small flap wheel or some emery cloth to get rid of any corrosion or ridges from the old bush collar.
Plenty of grease is essential!
Also worth noting is that the pivot bolt needs to tightened once the weight of the car is back on the wheels or you'll end up pinching up the bracket prematurely which in turn puts the bush under a constant twisting tension.

Just make sure they start to go in straight and even

This is the kind of insider knowledge that makes this site worth its weight in gold.

So in this case, would I tighten the bolts while the car's off its wheels and then torque them when the car's back on the ground?
