Polybushes - 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......?

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.

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???

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).

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.

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?

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

genuine poly ones do anyway. a bit like series damper bushes, in 2 halves,
but with a steel tube down the middle. pretty easy to fit and especially, I
think, to get out again, where standard bushes can be a PITA.
