I've gotten to the point that I will junk or sale this @#$%^&*&^%$#. Sorry, no specific meaning to the above, but I'm so,so pissed and tired. I have put so much money, time and work on my '93 ZJ and I still have the vibration in the front end at around 55. I have replaced EVERY SINGLE COMPONENT in the front suspension-steering systems. Brand new alloy wheels, balanced.... It is something so weird, sometimes it does it at 48, or at 50, 55, sometimes I get to 60 clean and nice and then,,it starts. Today I was doing just 50 in a straight line and started. Then I started to turn left to take a moderate curve and the vibration stopped completely! Now I'm thinking, Before all this started, I always noticed the front passenger seat vibrate side-to-side at 65, but never had steering wheel vib.. Now everything vibrates, I've had so many suspicions,, the control arms?, the "variable rate" coil springs? A couple of days ago, I got rid of the polyurethane coil spacers and put brand new rubber spacers, now it even feels a very comfortable ride but,,,I checked again and found that the front drive shaft has just a very, very little movement close to the transfer case. I don't really think that it would cause it. Could it be a damaged viscous clutch in the transfer case?. We know that the front wheels will fight each other or go side-to-side when in 4LOW if this clutch is damaged,, I don't know guys, please excuse this long thread, but I need some Ideas. Thank you all.
Yes, I'm going to remove the front drive shaft tomorrow and test drive. Hopefully all I have to do is replace the U-Joints on it, I really wish that is the problem, that's an easy one, after that,,,,,,,,,,,I don't know
it will only roll in park if he has the 249 transfer case
Definately use your ebrake. when I first bought my 95 zj, i drove it home from where i bought it, about 45 miles and parked it on my driveway which is a little bit steep. Nothing happened until several hours later when I was walking past my window and was shocked to see my new jeep in the road.
