Ive searched trailing arms and it seems many have the issue of cracked bushes.

The last set i got cost around $76 for 4, pain in but to install but overall not hard, but only lasted 6months!

Every time the center shaft separates from the rubber and the rubber cracks.

Super pro bushes are pretty cheap and curious if others have used Polly bushes in their trailing arms and what was the result. I dont expect them to last as long but might be easier to install.

I recon the rubber ones dont allow much up and down movement and all that stress is taken by the rubber in the bush twisting, and on corrugated roads and esp towing my new camper they just tear themselves apart.

I will also have to find the correct size if go polly.

I checked mine out when i put springs in the rear, and they looked original and fine. Not sure what your doing to yours but i haven't seen many having issues.

Yeah, I don't know what's going on, its always the front chassy ones going.

Might be the.rear end not.being.centered properly as have adjustable pan rod.

When you torque the center bolts, is the suspension at full droop, or is it supporting the vehicle? You should be doing it with the weight of the vehicle on the suspension - put jack stands under the axle, and remove the ones under the frame rails before torquing the bolts. Torquing with the suspension at full droop will result in the bush being stressed with the vehicle at rest and is possibly the cause of your problem.

Poly bushes are not bonded to the sleeves like rubber bushes, so they will allow rotation around the center bolt but will resist twisting - in other words - they will allow the axle to move up/down in it's entirety, but, will impact a one wheel up, one wheel down type articulation.

Bits4vits in the UK can supply these - be warned - they have a tendency to squeak (and wear) unless lubricated frequently. .

Thanks i torque the bolts with a jack under the rear axle,, but slightly lower than what it would be with the wheels on the ground..
