Front lower suspension arms

Post by Alastair » Sat Jan 06, 2018 12:15 am

My 1989 bx needed new front suspension arm bushes..... Removed arms drifted out bushes and fitted new. Re assembled. About two weeks later the near side bush is falling apart, so I replace again and re assemble .....again two or three weeks everyday use, and same failing of replacement bush.....Anyine any thoughts as to what I have done wrong?

Here are a few things to consider, where did you get the bushes from and how much did you pay? Cheap bushes from the likes of eBay at £6 each are poor quality. Is there a chance you may have damaged them pressing them in by pressing on the inner bush not the outer sleeve? Or perhaps you may have done the long bolt up too tight restricting movement of the arm (this will tear the bushes apart as the arm moves) For the sake of £30 odd quid a side I find it easier to buy new arms with bushes and swap out both.

Hi The bushes came from a motor factor, I fitted a full arm on the passenger side, but could not get a drivers side one so fitted bushes...twice to the rear! You mention tightness of the long bolt/ pin..... I note mine have nyloc nuts on the front and normal nuts on the back..... Is there any sort of special tightening sequence to them or anything?

The main thing is not to tighten the through bolt until the car's back on the floor at normal suspension height. If you tighten it while the car's jacked up, the bushes will be under too much strain in normal use.

Thats correct!
As your car is elevated on jacks or something, the suspension is fully loosen. And its McPherson Axle - if you tighten the nuts while suspension is loosen, you torsion the rubber bearings to a wrong position. You have to let the car stand by itself on normal / driving position and then tighten the nuts (both). Thats pretty normal for every car with McPherson front wishbones / common problem. I once did same mistake at my Daimler 203SC, wishbone rubbers were broken again after about 500kms.
Sorry for my english!
Btw i experienced that it is much easier to left the center bolt installed and working around while installing the wishbone. At least with small engine and small gearbox it was no problem there. And because its two nuts on both sides i used to center the bolt and readjust it after some driving / cornering.
Wish you could figure it out,
greetings
