Front grinding/rattling noise 2008 WK 3.0L CRD
 
Hello all,

I've been hearing a grinding/rattling noise near the front end of my Jeep. Replaced the differential fluid. Was at proper level, but wasn't sure if it had the limited slip additive. Still making the noise, and thinking this rattling is due to that shown in the video.

Its only the quadra drive system that seems to require the limited slip additive
Jeep Grand Cherokee WK - Maintenance information and schedules

Do you have an aftermarket lift kit installed on your jeep? Those have been known to contribute to front drive shaft failure.

How many miles on your jeep?

I do have the Quadra drive II. No lift at all on my jeep. About 96K miles. Recently replaced rear differential ring/pinon to get rid of whine, but this noise up front is more concerning to me. It sounds like gears are loose, but maybe the driveshaft?

Another angle of play.

Grinding is most noticeable decelerating quickly at high speeds. Really sounds like gear in front differential, but I'm new to diagnosing mechanical problems.

Well if you have quadra drive, then make sure you put in the limited slip additive as described on the wkjeeps link i posted.

I will be under my jeep on the weekend so I can check and see if my front drive shaft has the same amount of play in it.

I checked the front and rear drive shafts last night and I would say i have the same amount of play (both noise and movement ) as you show in your video. So i would say that you have to rule out play as being the cause of the noise.

Awesome. Thanks for remembering to check. That is good news. Still continuing my search. Can I inspect the front diff by just removing by the front bushing mount, then removing bolts? I wonder what else it can be. Because it sounds similar to grinding gears/clicking on idling deceleration.

Inspecting the internal components of the front diff is a lot of work to get access to. I have done it once and it took about 3 hours to remove the front cover for my first time and unless you are an expert in gearing, you wont know what to look for.

Hi Marc, the grinding is only during deceleration ? Ever ? I'm too with noises in front of my 3.0 crd.
