Baloo

I have tried everything. Alignments, road force balancing, rotation, roadmaster upgrade, etc. No matter what I try or replace, I have a "shimmy" going past 65 mph.

Anyone else have a similar problem or suggestions what to check?

Check and see if the steering rack is moving, the bushings could be worn. Get underneath and try moving it by hand, and also watch it while someone turns the steering wheel.

Replacement urethane bushings are not very expensive.

Have the replacement bushings, however there appears to be no wear so have porcrastinated doing the job,

You can check the rack but chances are they aren't bad. I have a 2000 and they were fine. I did replace them though. Just had the same problem with shimmy at high speeds, I had a small hole in my CV boot and now replaced the axle. Seemed to take care of it. Im not sure of your current configuration,"lifts or anyhting" but try the wheel bearing trick. Grab the top of the tire and pull it back and forth towards you and see if there's any play. You can also do it off the ground. It'll make easyier if you have oversized tires. Good luck! Peace.
