my 97 disco likes to wander a little. it seemed to get a worse with lift and bigger tires.does anyone know of particular bushings that may help.I was looking for poly bushings,but apparently energy suspension doesn't do rovers.I think i may need trialing arm bushings, but not sure what else or where the best place to get them is.

Once you lift there is an increase tendancy to wander especially under braking. My own biased opinion says that the stock bushings are the ones to stick with, and that my own vehicle would have done well to have had the bushings replaced at 75k. As bushes get older they do become less flexible, a condition that is worsened as temperatures drop.....

You probably need to adjust y9our castor or buy a tru-track

Lift + stock suspension = wandering. You probably will experience wandering with stock suspension. The radius arms and rear links I have from RTE are castor corrected to prevent this.

If you had wander prior to the lift, and after lift it has gotten worse, I would check the front end alignment, as well as check tie rod ends and steering control linkages for play. You should also check the panhard rod for play. (easy test is to push against vehicle on drivers side fender and feel for play in the body movement.

mike

a 2"-3" lift results in a 3-5 degree angle loss in your castor. some vehicles are more prone to a greater degree loss than others. stock is 3 +/- .5 degrees and with a fresh lift you could be looking at as much as a -.9 degree castor. the correct way to fix is with a set of castor corrected radius arms. A trutrac is always an curious option, but does not correct the bushing bind issues related with lifting these vehicles.
do as Joey suggests, get a local shop to do a 4 wheel alignment and they will be able to point you to the problem. but i'd bet money on it being castor related. for what it's worth, i'd save $250 for a set of rovertyms radius arms and be done with it forever.......
when i threw gages on my 99' it was -2 degrees and even with a detroit/ truetrac it still wandered like a madman.
in any case, it needs to be fixed, these vehicles at high speeds don't need any extra help at being dangerous.

And, if you decide to re-bush, as I did @ 77K miles, stay with rubber, you won't be sorry and really improves the ride.
I agree with Marc, castor issue probably, first get toe aligned.
