I had my rear diff go and it was making a clunking noise. The noise would only happen when turning and only when the car was good and warmed up. It was tough to tell where the noise was coming from, seemed like it was more from the middle of the car than the rear. Might be worth a look. Good luck.

 

well wouldnt I notice something in the driving ability of the car if that happened??? How do I pull the t-case oil out?

 

The drain plug 18 or 19mm. I would pull the plug and plug the hole with my thumb as I inspected the magnet on the plug. If no metal than I would replace it back.

 

my noise was definitely front right corner

 

well my gear oil is only a week old, but if i'm pullin the plug i'm changing it

 

TRE uses a Heavy duty magnet, so it could have picked up some of the larger chunks! check it, and forget the doughnuts! you got lucky!

 

Not so fast.... NOLIMITS has our famous self healing front differential

We all must remember that the front differential is inside of the front differential carrier assembly and the oil that comes out of the transfer case drain plug is only lubricating the ring & pinion and the tapered roller bearings that supports these two items. The magnet that I install on the bottom inspection cover will only attract crud from the ring & pinion gears as they wear but not from the front differential.

As for the front differential, it's located inside that carrier housing that the ring gear bolts to and the oil that lubricates it comes from the transmission. Any carnage that occurs inside that carrier housing will eventually make its way into back into the transmission.

*Note: If you have FUBAR'D or "think" that you damaged your front diff you must not drive the vehicle. Instead you will want to inspect the action of the front differential by jacking the front tires off the ground and turning one of the tires forward. The other tires should rotate backwards without any binding, clunking or tight spots.

Back to NOLIMITS self healing diff....

The odd behavior is an indication that the front diff indeed has a problem. I wouldn't risk contaminating the transmission or worse causing further damage to the front differential and carrier housing.

ok just read this and ran out and did it.

PASSED THAT TEST WITH FLYING COLORS!!!

JON, your t-case is no joke!!!! Thumbs up for a great product built by JON from TRE!!!

 

Let's not jump to conclusions. Something is obviously wrong and if the TC took a dump I doubt anyone would critique Jon. You are not supposed to do donuts in an awd. It would be not fault of Jon's if it broke.

 

Have you checked your wheel lug nuts to see if they are tight? You'd definately get a clunk from that... .

 

i know this sounds stupid, but your plastic cover over the wheel didn't come loose and rub the tire did it? you would believe how much it sounds like grinding/clunking when that happens.

i know its dumb, but something i would check out.

 

I vote this as well. Happened to me lowering a car once. When I removed the shock and strut the rotor fell top out away from the car and it popped out of the "socket" as it were. I had the hardest time getting that bastard back in. Clunking when turning and not when straight has got to be CV related.
