pop3 Posted December 16, 2007 Share Posted December 16, 2007 I have some squeaky rubber suspension bushes on my pickup. I have tried WD 40 and the Thai equivalent but it soon dries up and the squeak is back, I know I could use engine oil or a mixture of engine oil and diesel and it would last longer but engine oil can destroy the rubber and make it very soggy over a period of time, Does anyone know of a way to stop this annoying squeaky problem ? What about this silicone spray ? Link to comment Share on other sites More sharing options...
Crossy Posted December 17, 2007 Share Posted December 17, 2007 A silcone lubricant (rubber compatible) is the best bet, avoid anything like mineral oil that may attack the rubber. Link to comment Share on other sites More sharing options...
terryp Posted December 17, 2007 Share Posted December 17, 2007 A silcone lubricant (rubber compatible) is the best bet, avoid anything like mineral oil that may attack the rubber. Brake fluid...but it is mineral based Link to comment Share on other sites More sharing options...

wilko Posted December 17, 2007 Share Posted December 17, 2007 (edited) Are you sure it's the bushes? Usually sign of worn shockers or bushes - when the suspension moves there's a lot of parts moving together. I'd get the whole assembly looked at..... are you getting uneven tyre wear? E.g. on the outside or inside....does it pull to one side when driving or braking....do you get wheel-wobble after some bumps in the road? BTW - I had all my front bushes replaced for about 5000 baht - not going to burn a hole in your pocket. Edited December 17, 2007 by wilko Link to comment Share on other sites More sharing options...

pop3 Posted December 17, 2007 Author Share Posted December 17, 2007 are you getting uneven tyre wear? ..................... Yes I have noticed the tyres have worn on the inside but all the joints seem to be ok ? Good point about the brake fluid, I know it's ok with rubber but I don't know if it would be a good idea as maybe it would eat away the bolt going through the bush ?

mijan24 Posted December 17, 2007 Share Posted December 17, 2007 are you getting uneven tyre wear?..................... Yes I have noticed the tyres have worn on the inside ( more than likely needs a front end alignment ) but all the joints seem to be ok ? Good point about the brake fluid, I know it's ok with rubber but I don't know if it would be a good idea as maybe it would eat away the bolt going through the bush ? As Crossy suggested "Brake Fluid" yes. or even better Silicon brake fluid by the time brake fluid ate through the bolt you will be old & gray or at least older & grayer. Reminds me of the time one person raised a concern about the possible ill effects "playground copper logs" it was establised that the child would have to consume evey log in the playground before any ill effects would be noticed and considering the time this would take most probable ill effect would be indigestion not poisoning.

Lickey Posted December 17, 2007 Share Posted December 17, 2007 Pop3, sounds like you are using a pick-up for what its meant for, carrying loads, unless its old and used to carry a good load before you bought it, Todays isolastic rubber bushes only move within themselves, it seems you know how to eliminate the problem with some spray, can you tell us where this is please, also a shock-absorber check might be worth while, knackered shockers will cause the main suspension to move more, causing squeaking, try pushing down with your body weight on each corner of your pick-up, if it comes up after you release and dont bounce, shockers should be ok, but if it does bounce, shockers are knackered, BTW, brake fluid wont harm steel, but it will take paint off, and also be very careful using it on suspension bushes, the rubber in a brake cylinder is of a different make up to that in a bush, Rgds Lickey.

wilko Posted December 18, 2007 Share Posted December 18, 2007 If the bushes are worm the suspension geometry can be out and this can be a cause of tyre wear....you could get the wheels aligned (300 baht) but it won't last for long unless the bushes are replaced....they might tell you they can't do it properly or just do it and hope for the best. Basically suspension doesn't squeak....unless something is wrong....be it minor or major. If the vehicle is being used as a pick-up or is 5 years old or so...just get someone to look at the bushes.

455HOGOAT Posted December 18, 2007 Share Posted December 18, 2007 I Had an old Granada...A mixture of washing up liquid and water done the trick for a while. Cant remember how long it lasted but it had to be done on a regular basis.. Link to comment Share on other sites More sharing options...

Cant remember how long it lasted but it had to be done on a regular basis.. Long enough to sell the motor, along with the banana in the gearbox (yes, it's very effective) and the hypoid gear oil in the sump (does wonders for the oil pressure for a few miles) :) Link to comment Share on other sites More sharing options...
wilko Posted December 18, 2007 Share Posted December 18, 2007 W/U liquid is a very useful lubricant and has got me out of a squeaky situation more then once....but it has one property in particular that makes it very useful or very problematic.....it's soluble in water.

Gary A Posted December 18, 2007 Share Posted December 18, 2007 I agree with the soap. Soap, NOT detergent. Years ago I used to help out in a garage and spraying that soap on all the rubber parts was part of the service. It was the same green liquid soap that they use on the bead of a tire when changing tubeless tires on the rim. Link to comment Share on other sites More sharing options...
pop3 Posted December 18, 2007 Author Share Posted December 18, 2007 I like the soap idea, should be ok in the dry season ! As for the question before about the pick up being used for what it was made for, or maybe its old ? yes to both, its in good condition but is a year 2000 model, and it does get used for some serious loads of builders rubble ect at times Link to comment Share on other sites More sharing options...

micksterbs Posted January 2, 2008 Share Posted January 2, 2008 If your tyres are wearing on the insides, your tyres are toeing-out. You need to get your tracking checked. Also, if you do get your bushes replaced, make sure the guy/s tighten-up the bolts when the suspension is in the "at-rest" position not when the suspension is hanging free whilst on axle stands or on a wheel-free ramp. Any sloppy mechanic will do it then and when they bung the wheels back on and let the car down, your brand new bushes are under load exactly when they should be at-rest.
