    OPEN RECALL

    Yeah, just what I want, some 16 yr old going through my wiring. There is absolutely no competence left out there. Screwed each and every time I rely on someone else to lay a hand on my vehicles. Airbag would go off during the "repair" and Id get sued for injury and punitive damages by some blue...

    Tool to disable tpms all together

    Sorry to be so late to the party, but my TPMS delete setup is still going strong! I hardwired mine and put the control board in a new project box that also houses the 12v to 5v step down unit. I had one occurrence last year that it lost signal and threw a light on my dash but after resetting it...

    Rear diff fluid

    I hear a lot of diff noise at 70 MPH + but my Tahoe only has 74k on it.

    Rear diff fluid

    How much differential noise is normal? Im getting a whining noise at around 35-40 MPH now after the shop replaced the pinion gear. I dont remember what normal sounds like. Can anyone here actually hear there rear end through certain RPM ranges?

    Rear diff fluid

    Pretty sure a GL5 is a RPO for "FLEET INCENTIVE CHAMBERS RENT A CAR" not an axle or gear?

    Rear diff fluid

    Ill try... LOTS of heated debate and confusion out there about this. It doesn't help that GM used the G80 RPO code to designate both posi/limited slip differentials (on cars) AND Eaton Gov-Lock locking differentials (found on trucks). My personal conclusion after spending around 10 hours on the...

    Limited slip additive or not?

    This is not argued. Its the fact that it is not to be ran with a friction modifier that has people up in arms..

    Limited slip additive or not?

    Yeah, well its still not comforting when GM says..... "The use of any additive in locking rear axles (G80) is not recommended. Rear axle additives are designed for use in limited slip differentials which are normally installed in cars. All light duty trucks equipped with RPO G80 make use of a...

    Limited slip additive or not?

    The fact that the G80 RPO code is also used to indicate posi or limited slip differentials in car applications, but in trucks it is the Eaton Gov-Loc certainly adds to the confusion about all this but after 5 hours of Non-biased reading last night I feel I have sifted through the BS and...

    Whining noise through acceleration HELP (VIDEO)

    Spent about 5 hours last night reading and scouring all corners of the net on this issue, even letters from Eaton from people who have written them about it. Any additive in the G80 is considered a contaminate and should be flushed and refilled with strait up Synthetic 75-90. Here are just a...

    Whining noise through acceleration HELP (VIDEO)

    Just finished reading the entire internet about whether or not to use the friction modifier and the answer is NO. The pinion seal was not replaced during the first fluid Change 2 weeks ago before the noise started. They just unbolted the cover, cleaned and replaced it and filled it back up. I...

    Limited slip additive or not?

    So,...did we ever decide whether or not to use an additive on a G80? My shop just added it to my G80 rear along with DELVAC 1 75/90. Did they mess up?

    Whining noise through acceleration HELP (VIDEO)

    So it looks like I need to take it back and have it drained.....what a PITA! Edit: Nope, Ill leave it as is.. "The G80 is a limited slip differential that locks under certain conditions. It is made by Eaton and is nicknamed the Eaton "locker". Edit once again. Conflicting info even on...

    Whining noise through acceleration HELP (VIDEO)

    Heck, if they added the limited slip additive the first time I brought it in for a fluid change, could that have cause it to start whining and damaged it?

    Whining noise through acceleration HELP (VIDEO)

    Thats what Im trying to determine for sure. Does a 2007 Tahoe 4x4 with a G80 rpo code have limited slip diff? .....or is it a locker?

    The invoice above says the did. This is my question. Should they have put it in or not?

    G80 rpo in cars means it is a limited slip... G80 in a light truck means its a locker... Right? They should not have put an additive in my diff? @swathdiver
