hatmaker Well turns out that the transmission mount has gone out

hatmaker Ok i did an inspection today on my trans lines and 4wd shifter and everything looks good and feels tight and i did have one tran line popped out of its clip and u popped it back in but i still have this knocking, u dont believe its the 4wd shifter linkage because it feel like its coming from the trans area

Water Dog See if it will shift into 4-wheel drive. If the shifter handle doesn't have any resistance, your tc shift linkage has come apart. When it happened to me, I popped it back together only to have it come out again....turned out it was a bad tc mount (separated) allowing the transfercase to shift and pop out the linkage. Once I replaced the mount, all was good.

I can feel it knocking underneath my center console and it only last for a few secs and it only does it bad on inclines and it happen from a start on flat and when i hit bumps, its a knocking noise that actually vibrates the jeep a tad ... That is bout it

Ryman12 Try removing the rear driveshaft and driving around in 4 hi for a while. If the vibes are gone then its safe to assume the rear DS u-joints are bad or perhaps a pinion bearing. Did you install a SYE kit?

MuddyHell I replaced my rear driveshaft u-joint and that stopped the drive-line vibrations for me. The steep angle the lift puts on the joints is hell

I had a transmission line come off it's metal clip and it was taping on the frame and the acceleration knocking problem was due to my transfer case linkage after I put on the lift. I just replaced the whole linkage with a Novak shifter cable, I haven't had the problem ever since.

Rolf I'm guessing that there is a suspect u-joint on the rear driveshaft.

Vibration in driveline somewhere upon accelerating

I cant figure this one out. I put my 3 in suspension lift on bout 3 months ago and everything was fine. after about 3 weeks I had a vibration start happening when i accelerate from stop but quits almost immediately. So thinking it was just something that came loose i went back through my jeep and re torqued everything back down to spec. the same problem still occurs, i am stumped on what it could be. what do Y'all Think?
