Car Forum / Land Rover Cars / April 2006Polybushes - Again.......
Right. Spent all evening getting the old bushes off/out of the rear lower link. Ive got the new ones in, but at the chasis end, it is now a couple of mm wider at each end due to the bush. It now wont fit into the bit on the chasis as its too narrow. Am i doing sommat wrong here......? Mark 9090 > Right. > [quoted text clipped - 4 lines] > > Am i doing sommat wrong here......? No. Squash them with a G-clamp, leave them for a while to "remember" the new shape then remove the clamp and slide them in pronto.  SignatureEMB And talking of Polybushes.... What are they REALLY like - several people in the know - including some desert racers I know of - say that standard bushes last much longer!!! Also they give a better ride and absorb more vibration in the rough. Is all this true??? > > Right. > > [quoted text clipped - 10 lines] > -- > EMB > And talking of Polybushes.... > [quoted text clipped - 4 lines] > > Is all this true??? My opinion (and there will be plenty who disagree with me) is that the relative merits of both bush types are dependant on application. Certainly the standard bushes transmit less road noise and harshness than urethane bushes and outlast them in normal use. However extreme use seems to push them beyond their limits of elasticity in which case urethane bushes seem to have a better lifespan. I think that a lot of the bad reputation that urethane bushes have got is due to people buying them based on price rather than quality, and thus getting a less than optimal product with lifespan and quality issues. Being NZ based my supplier recommendations are local based but I expect that they will have UK agents. I have had good results with both Nolathane and Noltech (a company started by the original founder of Nolathane after he sold that company). http://www.nolathane.com.au/ http://www.noltecsuspension.com/ SignatureEMB Years ago when working around N Africa on survey work we went over to polybushes as they lasted longer, and were easier to fit under desert conditions. However there were (are?) various grades and it was said that the hardest grade (yellow in those days I think) were so hard that the holes they were fitted into would wear in preference to the bush. I believe current thinking is that for UK use original rubber bushes are best, provide you have the means to change them. Gordon >I believe current thinking is that for UK use original rubber bushes >are best, provide you have the means to change them. I've never done a polybush but have done normal ones. Are polybushes a lot easier to fit? I've often seen this said but have never understood why they would be easier if they are harder wearing? >> I believe current thinking is that for UK use original rubber bushes >> are best, provide you have the means to change them.

They tend not to have the outer metal 'barrel' that requires pressure to fit. They can also come in two bits & just slot in.

SignatureAustin Shackles. www.ddol-las.net my opinions are just that "Chuck didn't reply, so George swung round in his saddle. He could just see Chuck's face, a white oval turned toward the sky. 'Look,' whispered Chuck, and George lifted his eyes to heaven. (There is always a last time for everything.) Overhead, without any fuss, the stars were going out" Arthur C.
