3rd Gen 1500 owners beware!!!!

This is the 3rd truck I've seen with an issue similar to this. Slight vibration when turning at higher speeds, vibration when driving fast, and a clap in the rear. I went under my truck yesterday. I jacked it up in my backyard, put 2 jact stands under the rear axle and put in in drive to ab 55 and found the vibration was still there... looked under the truck and the drive shaft was wobbling. Upon further inspection I found the 4 bolts holding the drive shaft to the rear diff were loose. In fact 1 was missing. Tightened the 3 remaining bolts and bought 4 new ones from my local dealer. Please make sure your 4 bolts are tight

In my 21 years as a dealership technician the only time I have seen these bolts come lose is if someone did not torque them correctly or put Loctite on them like they come from the assembly line. I have seen them break before from being overtorqued.

Yes I did put loctite. I always put something on bolts whenever I do work to anything really. Be it loctite or never seize. Thinking ab u joints. They both still seem fine though. I'll order them and change them when I notice them get bad

Glad I found it definitely but what a shame it got to that point. I've seen 3 trucks total with this exact issue... could definitely be that they had work done to them and weren't torqued down properly, but I havent done any driveshaft work since I got it so it really doesnt make sense

A racer I knew years ago(in 1973) had a 1973 camaro pro stocker that lost the driveshaft at 143 mph.Ain't never ever a good thing to shed a part.Torque it,glue it but make sure it stays.And he never raced again.His disability check was always on time.
