Steering Wheel shakes at 80 to 90 kms had the front end checked all is good so they rebalanced all 4 tires said one on the front off by 2onces and everythings is now ok ,drive it home startes shaking again samething as before call them back told me to bring it back in again for another road test i would think the dealer should be able to find and fix the problem by the way cost me $233.00 with an oïl change and air filter help please

 

I would check all bushings on the front end, stabilizer, ball joints, and wheel bearings for play... A little play in any of it will cause a whole lot of shaking under the right circumstances. My WJ has some deathwobble still, and I've already spent almost $800. That only solved half my problem... I still need to replace the ball joints on the driver's side... I have a thread here somewhere with lots of death wobble info. Well worth reading...
Keep us posted.

 

switch the front tyres for the back ones and see what happens, shakes at that speed are nearly always balance issues.

 

I found only ONE place I can highly recommend that KNOWS how to balance tires. That is Bernard Tire Shop (St Hilaire) maybe the other branches too but I only have dealt with this one. They do truck tires, so its right up their alley when your tires need balancing. If their in other provinces I cannot say, but check out a truck balancing shop.
