Rear suspesion overhaul

Postby paulrob100 » Tue Oct 10, 2017 7:31 pm

When I bought my GTA, two and a half years ago, there was a slight knock on the nearside rear suspension. The knock has not got any worse but the rear suspension is now creaking & squeaking. I suspect that this is because the car is garaged & has not seen a wet road since I bought it. I cant tell if its coming from the wishbone bushes, the antiroll bar bushes or the springs / spring seats.

Anyway, I have decided to sort it out over the winter, there is also an oil leak, I think from the gearbox / driveshaft seal, so that might as well be sorted at the same time.

Where to start ? Is there a complete bush kit? or do they have to be bought separately ? Certainly there's a lot of them. Can the hub assembly be removed complete with the driveshaft ?

Just some preliminary thoughts :thinking :thinking

Depends how old the bushes are as to whether they need full replacement.

Supposedly there was red grease between the two parts of the bush (top hat design)

See page 2 re grease. I'm not sure how practical it is to open up and re grease them when they're worn or old.
I'm just here for the gasoline.

Thanks Darren, that's really interesting. The car seems to handle ok. Its just really annoying, as there are quite a few speed bumps in our town, & its seriously uncool :down .. I might start with the A/R bar bushes as they seem easy to do & see what happens.

Maybe its time for a coil over kit too, that will take the shock absorber bushes out of the equation.

Trial & error :crazy

Since the day I picked mine up unless I'm driving on anything other than glass smooth roads the back of the car knocks like it's full of illegal immigrants.
No play in anything, nothing loose, have never yet managed to figure out where the hell the knock is coming from apart from a loose fitting on the outlet for the engine bay fans which helped slightly
