I had been dealing with a bad vibration and clunk on my 2017 Grand Cherokee for weeks and kept putting it off because I was not sure where to go. I tried a general garage first but they just balanced the tyres and told me it was fine, which it clearly was not. Eventually I found a shop that does a Genuine Jeep driveshaft fix in Musaffah Shabiya (https://jeepservicemussafah.ae/driveshaft-repair/) and decided to give them a try based on a friend's recommendation. They put it on the lift, showed me the worn center bearing and a bent shaft, and replaced it with a new one. The whole thing took about half a day and the price was fair, not cheap but not dealer crazy either. The vibration is completely gone and the clunk too. If you are dealing with something similar, do not wait like I did. Just get it checked properly before it turns into a bigger problem.
