Re: Squeek from rear suspension
There are no grease nipples as I know of, I've just upgraded some of my rear bushes to the polybushes ( powerflex bushes ) because they were worn and it failed its MOT. The powerflex bushes are much more harder wearing also.
I think there are about 14 rear bushes to check, 7 on each side - somebody will correct me if I'm wrong I hope. The best way to check to see if there is wear into the subframe is to get underneath the car - if possible put it on a ramp. I had a good look at mine whilst it was having its MOT being done - you can easily see which points get eaten away by worn bushes.
If your getting sqeeking the chances are it is the bushes that have worn. I wouldn't risk not having them checked out either by yourself or at the garage.
Let us know how you get on.
Hope this helps.
