Hi, Ricafort!
 
I am sorry to hear you have been the victim of foul play. I suggest looking at the topics in the Chevrolet Blazer GMC Jimmy group. From your description, I can't tell whether it's a differential problem but you may have better luck with a more suitable topic. If all else fails, give Got a Quick, Technical Question? a try.
 
Good luck!

Update! I took my car in for a serious diagnostic. Test after test, they've concluded that my my gasoline mixture in the tank has higher Octane content that of the gasoline station premium 91, In otherwords, when my mechanic tested the gas sample off my tank he said that I have high concentration of octane to which my car engine can blow up anytime, due to the O2 sensor and the CMFI can't take it. That's why my car wanting to stall and felt dragging. my mechanic said that I should replace my gas tank cover with a lock. And yes, he also concluded a foulplay was involved. Just to be safe, that my car always parked inmy drive way, I've installed a nightvision cam and a dependable car alarm.

I need to change a gasket on my rear diff to stop a leak on my 1998 Jimmy. Until I change it I wanted to add some gera oil. This question may sound silly but where do I add it? I have looked all over the diff to find a plug with no luck? I looked in a Haynes manual for a pic with no luck?
Help and thanks.

I read that message but still did not read where the plug to ut the gear oil in is? The Haynes manual shows the back of the diff plate and how to empty it but not how to fill it? I was looking for a seperate plug up higher to squirt the gear oil in.

Look on the passengers side of the differential, forward of the axle and above the centerline. It will have a square hole that a ratchet with extension will fit in. You should be able to put your little finger in the hole and touch gear oil.

#22 of 22 Leaking Rear Diff. by tjw92

Nov 10, 2011 (8:06 pm)

I have a '99 GMC Jimmy and I have had so many issues with it since I bought it two years ago. Right now Im dealing with a leak from the rear diff. when its parked or driven. The bottom rim is saturated in oil. I took it into a shop and they said I had to come back in a week to get my rear end replaced for 900 bucks. Yea right, its not even making any noise, but I dont know why it is leaking so much. Can someone please help?
 
Also I have some play in my transfer case. I shift and it makes a loud clicking or abnormal shifting sound, Im not sure how to fix that. Its like the 4x4 is trying to kick in every time is go from P to R or to D. Let me know if someone has an answer to that too. Thanks.
