Problem with diff

[Samkia]

Hi everyone. Had a problem last night whilst stuck in traffic every time I let the clutch up the traction control on the dash came on and their was a clunking sound. Is this telling me I need to change the diff oil or something more sinister its the first time it's ever done it.

Mine does this, but its more of a grindy noise. Only does it when pulling away sometimes. IIRC 007 has the same problem and monfish checked everything and couldnt find a problem.

It's normally a sign of the diff oil needing changing, or sometimes it can be a worn driveshaft. If it only does it when the diff oil is hot then that is the most likely cause and the cheapest fix too.

I winner if its one side slipping and triggering tc

Thanks guys will order some oil on Monday. Like I say it's the first time it's done it and the clutch was only at biting point.

It does tend to be one side that slips when the oil isn't working properly. Sounds plausible for a TC light.

Trust me you will know if it's your diff, it makes a awful sound and feels rough to drive.

Holden put a 350+ horsepower engine into a car made for a V-6. Some GTO owners have suffered a failed differential, others have been lucky.
Depends on what day of the week it was built, I suppose.

My diff did the same thing and got really bad only when hot. Only had done 13k miles, in the end had a trutrac diff fitted.

Same here, much better

Is this an expensive job ? Could be me next if the second bottle of friction modifier don't work added to the purple stuff

Trying this today

Part is cheap 400/500 but fitting is a big job(labour)

This is good for those of us who don't hammer their cars, the diff isn't bigger, heavier and more expensive than it needs me.

Its a sad commentary on the quality of products. My GTO has 25,000 miles, and the never-abused differential is already making noise. I have had plenty of American-made cars, most with a limited-slip diff, and never an issue.
On the other hand, I had a 1976 Triumph TR-7 [with the Spitfire gearbox and rear] that blew several diffs and trannys, before I switched to a diff and 5-speed tranny from a 1980 junk-yard TR-7. Then the car rusted to pieces.
Replaced it with a 1980 TR-7 convertible with rust-proofing.

I think Monaro stuff is 7.5" crown, while vxr8 is 8.1 IIRC, Camaro 2010 diff is a straight bolt in and is 8.3"
I understand the ZL1 camaro is over 9" dont think thats a bolt in though.

Chalk another win up for the vxr8's
