Custom driveshaft after lowering?

[tdupont]

Anyone had to have their driveshaft shortened or a custom one made after installing a drop kit for the rear?

Put a Belltech 3-4" rear drop in my 03 Tahoe. Only have about a 1/4" between the end of the transfer case and the vibration dampener on the yoke. I can hear the tail shaft of the transfer smacking into the yoke all the time, come to an aggressive stop, then when letting go of the brakes, shift between 1st to 2nd and any aggressive downshift when smacking the throttle.

I talked to a guy at a driveshaft shop, obviously he can do it and understands what's going on. So, looking for insight. If I do end up having to have one made or one modified, I'm thinking about keeping the OEM one for future owner if they think about returning to stock height, and getting one out of a junk yard or off eBay. Just looking for some insight guys, thanks.

Have you checked all of your mounts? Motor, Trans? Is your rearend mounts nice and tight? I'm dropped same as you on my 03 and I'm using my stock driveshaft with no issues.

Not going to lie, I'm neglecting to check those mounts. I didn't have this issue until I dropped it, its a 4wd rig.
I'm definitely going to check those mounts now though to see if anything is out of wack before I drop a couple bucks on another driveshaft.

I know I'm chiming in kind of late here but...............I don't know of anyone who's had to replace a driveshaft after lowering these. @NORCAL SS would know better since he drops these things for a living, and I've never heard that mentioned, even with guys who go even lower than 3-4". I'd bet you have something else going on. Check any control arm bushings, see if the axle is moving around, or like Tonyrodz said, engine/trans mounts.

I'm chiming in WAY late here.

Have you done adjustable UCA and LCA to move the rear end back to its original position? I also don't see the LCA relocation brackets on Belltech's kit.

Late to reply now, couldn't find anything, had it looked over by the mechanic, didn't see anything.

Instead of shortening an extra driveshaft I picked up for it after I got tired of putting grease in the yolk, I bought a lq4/4l80e to drop in (of course after I throw a cam in and replace the majority of seals).

Turned into a debate of suspension being too soft, then rear caliper freezing, then engine mounts, but couldn't come to a conclusion.

Had a few different issues pop up so the occasional pop/slam wasn't quite concerning + I have other vehicles to drive.
