Transfer case drop question

Is it really nessery to add the transfer drop kit with a 2'' or 3'' spacer lift? I have more noise and vibes after installing it than I did without it. Without the drop I had no vibes and only a knocking noise when starting out in 1st gear. Sounds like something hitting the floorpan but cannot find it. Please help want it right!

Each jeep is different with a 2" lift you should not need one. Getting into the 3" area things get a bit gray, 4" yes. Thus do you have 2 or 3 inch lift? Which lift kit did you put on? Any additional mods, body lift as well etc?

All Jeeps are different but mine didn't need a TC drop. The knocking you are getting is probably binding in the TC linkage.

I had vibes with 2" bb. Did a drop of 1" and they went away. I swapped in a 1" MML in place of the tCase drop and I'm all good. Didn't like the loss of 1" clearance

My 3" lift required both a tcase drop AND an MML to get rid of the vibes. All Jeeps definitely are different.

Almost the same scenario for me, except I had a 2" suspension lift vs. a BB. Rather than dropping a full 1", I inserted a washer one at a time until the vibes were dialed out. After my MML, I was able to remove the washers and bring the skid back to stock height.

Currently I am back to running a 1" transfer case drop, but I still net 0.5" clearance over stock. I dented and mangled my OEM transfer case skid enough to the point where I upgraded to a UCF 0.25" skid. Despite the MML, after installing the skid, I discovered vibes at 30 mph . I dropped the skid 1" with square tubing, and the vibes disappeared . Because the skid is aftermarket, I still get better clearance compared to a stock skid. If I were to invest in a SYE kit, I would net even more clearance; however, funds are not permitting and I am actually quite satisfied with the current build specs and stage of my Jeep - based on the type of wheeling that I do.

Maybe cut the spacers in half. Best of both worlds.

Took drop spacers out and no more vibes! Still have a little knocking noise when dropping the clutch in first gear but I guess I'll have to live with it because I cant find it. I guess its one of those cant have your cake and eat it to deals. Thanks for the advise!!

t-case drops are 100% worthless to do. why lift a rig then lower the center of the jeep back to stock clearance. get an SYE and do it right.

I'm not sure if it's that absolute. A transfer case drop is so much cheaper vs a SYE kit. It does provide for a driveline and pinion angle solution for lifts < 3". Is a SYE the right way? Yes, but there are alternatives to realigning pinion angle, some are more expensive than others and some work better than others.

I don't have deep pockets so I built my Jeep according to what I could afford and for what type of trail conditions I wheel on. My Jeep suits my purpose and budget fine - it works. FWIW, I have a transfer case drop made out of square tubing but I still net 0.5" clearance over a stock plate .



Without the spacer, I would get vibes at around 30mph - now I don't. Does the dropped transfer case impact my wheeling?





Nope .
