Jeep Problems

Seabee_BUC:
I've been following this thread and I came to a conclusion. It sounds like if you have gone through two poly bushings then your entire driveline is moving way to much(i know...I'm a rocket scientist..LOL) Obviously most of the movement is during times of stress and flex. I would start tracking down the movement by beginning to look at how some of your major mounts are bolted. Check to see that the holes in your trans skid aren't all wallowed out allowing the whole skid to move, or even the actual holes that your MM are bolted into through the frame. I can't imagine that the movement of just the tranny or t-case is enough to destroy a poly bushing. Something just seems to be more severe. It could be as drastic as a frame crossmember cracked or broken away from one of the side frame rails too. Though its highly unlikely, its possible. That alone would give you lots of frame twist that would contribute to the problem getting into gear. Just a thought... ::)

HOT-ROD:
thats thinking out of the box. What about it roger? Hows your under carriage?

calvynandhobbs:
My undercarriage looks good. There's not even surface rust on any of the frame. I think I led you down the wrong path with my previous post. I have never changed the trans mount, but my Jeep does have a motor mount lift. What I have had to change is the rear driveshaft ujoint twice within the last 2 months.

This past Saturday was the first time I ever had a problem with being able to go into 1st or 2nd gear where the shifter seemed to be binding on the left side of the center console. I haven't had a problem with it since then. This is why I am questioning my trans mount at this point, but I do not know if it is bad or not yet.

The trans mount could have contributed to binding the rear ujoint if there is any slop in it. I also need to measure the pinion angle of my rear axle. By just looking at it from the side my pinion appears to be pointed up a little too far. This could be due to the fact that I have RE 4.5" lift superflex non-adjustible arms with only 3.5" lift coils all the way around. Would lifting it up that additional inch lower the pinion angle?

BayouGold:
Roger when i ordered my new springs (RE 4.5") i also emailed rubicon express about the length of their non adjustable lower control arms so i would know the length to set mine. Eric Ennis replied that their super flex kit lower control arms are 16" center to center. The same arms for both kits.

gearhead1985B:
when you checked the tranny mount how did you do it? if you just grab the tranny and shake it the body will flex the suspension before the tranny will move the way i do it is either move the tranny around with a crow bar or have some one else get in the jeep and apply a load (apply brakes and slowly let out on the clutch the torque of the motor will make stuff move) also this only happend under flex so check the body bushings they may be worn or the motor mounts may be bad 

here are the 2 different mounts that i tried
