i'm planning to change wishbone bushes with uniball bearing(like the ones used in wrc) to eliminate arm play. somebody interested?

something like this : http://midnight4x4.com/store/item/np-ub.html

Sure,Im interested,especially at that price.

My current Scan-tech Wishbones bushes are coming free of their own accord.

A timely solution me thinks

Just hope they make em in the correct fitment.

I'm not convinced it isn't the extra strain of the richmod that knackers those bushes Steve... I'd definately be interested in this, if I still had my Skye Rocket...

Don't do it... The rubbers are very important for the overall handling of the car. I agree if you want to reduce play and mount PU bushes, but uniball bearing are only usefull on very smooth surfaces, or for a short lifespan.
Within a year or even less, there will be too much play in the bearings.

I agree. You need to be very careful. The rubber bushes are aligned to give a certain response under hard acceleration and breaking which affects the tracking of the wheels.

They will also affect damping.

i am not so sure about the wearing of the ball bearing.... and the surface need to be used..... doesn't matter if on tarmac or gravel rally cars use succesfully that type of articulation...
anyway i will try.

rally cars get rebuilt on a regualr basis by big teams of mechanics with big budgets, sounds like a cool idea, but probably not really practical for day to day use.
let us know how you get on if you do decide to do it though!

i.ve spoked allready with some rally technicians and the facts was:
+ sharp steering, quick cormering without esitations, much much better life than normal bushes
- really bad confort, depends on road use, the chassis tend to crack/loose

another triangle design
