#12 of 21 GMC jimmy 1995 feels it is dragging a deadweight. by lnx26 Jul 24, 2007 (9:17 pm)
Hello Everyone, my name is Ricafort, I have a hemi-down car I had it for 4 years now. it's GMC jimmy 1995 vortec 4.3 V6 2 dr, 4wd. I had my transmission fluid flushed due to one bolt was lose and it was leaking. the mechanic told me someone was sabotaging my car, also found the ABS sensors are cut and rear wheel lugnuts are lose. I had all those problem fixed. recently, while I was driving home, I felt that my car was heavy seems like I'm pulling a trailer that when I take off my foot off the gas on the freeway from 65mph, my speedometer droped 3miles per sec and when I step on the gas to sustain the speed, car was jerking and hesitating and feels like my car my engine is whining and the car is dragging. it feels like I'm using 2nd gear.   Please help.

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!   tidester, host SUVs and Smart Shopper

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.

#16 of 21 Rear Differential question by northguybc Jul 28, 2007 (4:06 pm)
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.

Replying to: tidester (Jul 28, 2007 10:34 pm) 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.

Replying to: northguybc (Jul 29, 2007 7:30 am) 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.
