Bob Horner Posted September 28, 2015 Report Share Posted September 28, 2015 Ok, a difficult one this but looking for ideas...... Its a late tr4 with a revington suspension upgrade done about 12,000 miles ago. It has developed a banging from the front nearside suspension. It doesn't make the noise straightaway but after about 3 or 4 miles. Then it is a metallic sounding bang (or crack even) Once it starts doing it, you can sit on the wing and re create the noise by bouncing it up and down. Checked out damper (removed and still did it) , replaced top ball joint (could feel vibration in joint as it bounced up and down). Spring looks fine. When changing top ball joint noticed that one of the top wishbones was a bit stiff. Rebushed etc when kit fitted (not by me). I suppose trunnion next? Or top fulcrum? Anyway, any thoughts and ideas gratefully received. Oh and wheel bearings checked etc and fine. Bob Quote Link to post Share on other sites
Chilliman Posted September 28, 2015 Report Share Posted September 28, 2015 Bob, you sure the spring is good - sounds a bit like a bust coil to me Quote Link to post Share on other sites
Bob Horner Posted September 29, 2015 Author Report Share Posted September 29, 2015 (edited) I initially thought something to do with the spring as well (almost like it was catching in the pan and then releasing) I havent removed the spring, only the damper but cant see any problems. Drives normally, apart from the noise and if it was the spring i'd assume it wouldn't take a few miles to start making the noise.

BlueTR3A-5EKT Posted September 29, 2015 Report Share Posted September 29, 2015 Inner fulcrum bush lubrication - if it is fitted with poly bushes. Peter W Quote Link to post Share on other sites
stuart Posted September 29, 2015 Report Share Posted September 29, 2015 When you say its a Revington suspension upgrade exactly what has it been fitted with? Stuart. Quote Link to post Share on other sites
harrytr5 Posted September 29, 2015 Report Share Posted September 29, 2015 I had this and it turned out to be a new faulty trunnion.Only found it when a mate (thanks Howard) got down and viewed the up and down movement whilst I pushed and pulled to replicate the suspension on the road.Changed out both sides to SCP manufactured trunnions. (Moss sells them).Everything was new but the trunnions were of a different manufacturer that I did not recognise.Only lasted 500 miles!. Now no problem in that area 2000 miles on. Just my thoughts and what I found.May not be yours but may help. Regards Harry. Quote Link to post Share on other sites
Bob Horner Posted September 29, 2015 Author Report Share Posted September 29, 2015 Thanks chaps for the responses. It is fitted with poly bushes so inner fulcrum lubrication is an interesting suggestion (top r/h wishbone stiff when changing ball joint). What to lubricate with? Revington kit is the late TR4 polybush integrated kit with 160lb springs. Haven't fitted the roll bars or adjustable top fulcrums. Trunnion was probably next thought for me.

Regards Bob Silicone grease as supplied with the bushes. (known by its trade name of MS4 to those in the trade) Absolutely smother the pin and bush inner with the stuff before assembly. Plumbers merchant will do you a tube or aerosol of silicone grease. or try these http://www.ebay.co.uk/bhp/silicone-grease-plumbing You should fit the roll bar at the front as a minimum - you will notice the handling change.
