Trunnion Top link to Damper bushes

Post by **Pikey** » Fri Dec 14, 2007 8:24 am

My Pickup has had an advisory on its MOT. The Trunnion top link bushes have perished after only 5 years and only about 2000 miles (I dont do a lot of mileage). Ive bought a new complete link kit, consisting of new bushes the link pin and the various nuts/washers. My question is how much do I tighten up the nut, do I just tighten it up enough to nip up the bushes, or do I tighten the nut up until it stops (bottoms out), this seems to squash the bushes too much.

5 years out of rubber bushes is good going. Best to fit Poly Bushes and delay tightening the various nuts until the car is back on the ground with the weight on the suspension. I tighten the top pin nut to 40Ft/Lbs then knock over the tab washer.

My feeling is that the big washer should bottom out - but if the bushes (and yes Polyurethane for here are far better) seem to be overcrompressed, then stop - and lock the nut!

If you fit poly bushes and I agree they are better check that all edges and lips are smooth as its not unknown for them to be damaged by a sharp edge and dont forget to use white grease on them, unfortunatly the modern rubber is not as good as the old rubber that used to be available.
