'Whirrrrrrrrr' from my 3rd gen rear axle

[ash-ssrg]

Running the risk of getting the pi55 taken out of my description of the noise getting but.....

Only happens when I take my foot off the 'gas' pedal as well.

Am I looking at a rear diff problems down the road???

Cheers for any input,

Ash.

possibly yes, it may be worn, try a really good oil and a molyslip gearbox treatment. Could last years or maybe not. Worth sourcing a spare casually for the eventuality of it stripping gears on you. If it does then you can still get home in 4wd cos youll effectively have a front wheel drive motor

guess that holiday to New York is off!!!

Where might one find a replacement LSD diff for a 3rd Gen?? Am almost sure Halfrauds wont stock 'em.

And how long would a half decent spanner monkey take to swop it out?

BTW - rang up every motor factor in Warrington for LSD gear oil - it seems this has officially become extinct!!

You sure it's not just a knacked UJ? Is the noise definitely from the diff?

I believe Nero got his oil/fluid from the Difflock forum.

I believe Nero got his oil/fluid from the Difflock forum.

eventually, took 4 or 5 weeks after ordering, they didn't seem to keep it in stock either, and had to wait while it was on back order. ( http://shop.difflock.com/ls90-high-p...ial-p-104.html )

TonyN was stocking it for a bit, not sure if he is at the moment or not though....

Is this the right type of stuff down near the bottom of the page?

Btw, was that the fluid that honked a tad Ian?

Yep: Comma LSD gear oil at the bottom of the page.

Thats exactly what I picked up this morning from probably the smallest factors in Warrington who didnt have it either but sourced some within 24hrs.

Will drain the old stuff (if theres any in it to begin with), fill with new stuff and keep everything crossed that it settles the diff down.

Had comfirmation from my local mech. that its the diff - probably chipped a tooth and that if I get a 2nd hand repacement I would be looking at about £300 quid labour (Ballpark). Is this reasonable?

ASh.

update - changed rear diff oil (lsd type) the other day - no difference.
changed transfer case and front diff oil today - noise almost gone!

but still there - the plot thickens.
