Phil H 4 Posted July 28, 2020 Report Share Posted July 28, 2020 Hi My 6 has recently developed serious creaking of the front suspension. I fitted AVO shocks and springs from Revingtons with Super-pro poly bushes back in August last year. At the same time I replaced the anti-roll bar link arms, and fitted new bushes. The car has only covered about 1500 miles since then. Reading post back 2008-14 it's suggested that the creaking can be cured with silicone spray,has there been any re-thinking since then. Should the silicone be applied to the bushes at the top and bottom of the shock absorber and or the spring seat collar. Is it just a case of misting the silicone over the bushes or is any dismantling recommended. I have some 3 in1 Silicone Lubricant, assume suitable. Any guidance appreciated Thanks.

Peter V W Posted July 28, 2020 Report Share Posted July 28, 2020 Phil, Red rubber grease is used to assemble rubber bushes, seals and o rings. It preserves and lubricates. It also prevents creaking. regards Peter V W Quote Link to post Share on other sites
aardvark Posted July 28, 2020 Report Share Posted July 28, 2020 Phil i had a creaking noise which I put down to poly bushes. I tried various sprays for lubricant but in the end decided to strip everything down and regrease the bushes using as much silicon grease as I could get to stay in there. After putting it all back together the noise disappeared for a week then came back. After a nice trip abroad in the car on less congested roads I was able to pin point the noise, following much driving, to the front of the car. The noise changed pitch if I put my foot lightly on the brake. The noise came back after a short time but disappeared again upon light touching the brakes. Once back home, I swapped out the callipers for a rebuilt set and noise gone. The lesson I learnt was that even though I’d have put money on the bushes being the source of the noise, it was something unconnected. Also, I can say with much certainty that spray silicone grease cannot ‘wick’its way into the bush as the bush is a tight fit in its housing. All you achieve is getting spray everywhere other than inside the bush. cheers dave Quote Link to post Share on other sites
Phil H 4 Posted July 28, 2020 Author Report Share Posted July 28, 2020 Thanks Dave for the info. The noise is very apparent with the engine off and just bouncing the front of the car, which suggests it's the suspension but still to be investigated ! Was your noise there when the car was stationary? Phil Quote Link to post Share on other sites
aardvark Posted July 28, 2020 Report Share Posted July 28, 2020 Not really. I wasn’t able to locate the noise either back to front nor left to right until I was driving on near deserted roads. The noise seemed to be coming from everywhere. Even then I was adamant it was bushes but was proved wrong when I stripped them down. my bushes were super pro too. I got some more super pro grease from eBay. I also got some of Revingtons special brew packet bush grease - looks like salad cream - they told me it would cure any squeaking bush .... ooerr Missus. anyway, I spent a weekend stripping out the bushes and regreasing using both the super pro and the Rev special brew. This gave me an insight into how good the spray silicone was as I could see nothing had penetrated the bushes when I had previously sprayed them. if your squeaking occurs when stationary then either your bushes are very dry or you might have a cracked chassis I hope it’s not that. good luck with it. cheers Dave Quote Link to post Share on other sites
harrytr5 Posted July 29, 2020 Report Share Posted July 29, 2020 On my complete rebuild of my TR5 and using poly bushes all round I got a creaking sound from the nearside front. Turned out to be unbranded trunnion and the bolt hole offset. Soon swapped out for branded ones (SCP) If I recall correctly from Moss and no problem since.

Phil H 4 Posted July 29, 2020 Author Report Share Posted July 29, 2020 Tried the silicone route this morning, quick 50 mile spin and all quiet for the moment. Fingers crossed. Phil Quote Link to post Share on other sites
Z320 Posted July 29, 2020 Report Share Posted July 29, 2020 On my TR4A I didn't want to believe it! The noise was from the front shock absorbers, the rod sliding through the seal. With NOS Monroe absorbers - noise gone. Quote Link to post Share on other sites
John McCormack Posted July 30, 2020 Report Share Posted July 30, 2020 I have a knock from my front suspension/steering. It occurs when the load is off the right wheel i.e. turning right, but it doesn't happen all the time. I have new suspension bushes throughout, rebuilt steering rack, no apparent play in tie rods or top ball joint. New shocks and they are tight. Yesterday I tightened the brackets for the inner wishbones. It is till there. Quote Link to post Share on other sites
Z320 Posted July 30, 2020 Report Share Posted July 30, 2020 Hi John, years ago I had exactly such a knock! After re-tightening the falcrum pins I forgot a ring spanner on one of the bolts. Luckily iI didn't fall off by itself.... Ciao, Marco Quote Link to post Share on other sites
