<< < (3/3)

extreme90:

been on a year now had some serious grief and they now i need to replace 3 of them and thats it the rest are all ok
i agree with tim, no vast inprovement over stock bushes
just is they that easy change

Range Rover Blues:
The colour just depends on the mood of the moulder, it's a dye.

Manufacturers like to use colours to denote the stiffness of the polyeurathane, it's measured by shore hardness, being perhaps 25% harder than rubber.

Deflec ones from Paddocks are currently Orange, the same bushes from Rimmers are black.

Some are red, some yellow and some blue.

I find they tighten up the handling on my lifted Rangie, less body roll.  i can understand the wear in the bush mounting if lots of crud gets in there and works like a grinding paste, poly itself is very wear resistant due to it's compliance.

Anyway, as a general rule I think extreme off-roaders/racers/trialers like the durability and compliance (softness) of OEM rubber.  Remeber that there are 2 types of radius arm bush, Defender and early RRC use a single rubber element, later (EFi) Rangies had a dual rubber, with an intermediate sleeve to stiffen the bush and help with body roll.  These might have reverted to the softer bush when Anti Roll bars were intorduced but not on my car.

Those of us who use our cars more for leasure like the serviceability of poly. I changed my Panhard rod polybushes because they were 2 years old, no sign of wear and no deterioration due to oil contamination (another failing of rubber) but I changed them anyway.  It cost £4 including new sleeves.
