I’m not referring to the misses! This is something more relevant....
My 2000 P38 makes an every increasing mid tone whine from left side of vehicle but only when I’m not accelerating. The tone is higher at faster speeds and conversely, as I slow down, the tone decreases until it disappears at about 5MPH. It’s not the exhaust.
Both rear hubs, rotors and brake pads were changed in June of this year and I don’t believe that these are the cause of the sound. Tyres are newer since November.
Not much else I can type to describe the condition so....... any ideas?
But like telling doctor w]you have a pain but only when you walk.... what’s wrong?

I’m going to guess a diff, probably pinion bearing.

+1 on diff. The torque when accelerating takes up the slack so it stays quiet.

OK.
Well thats a nice Christmas surprise.
Any ideas as to what I can expect on price for it to be rebuilt?

I feel it's worth pointing out that my P38 had a whine like that at the back when I got it, and six years and nearly 100,000 miles later it's just exactly as whiny as before.

Fair enough gordonjcp...... but question must be asked, is this a potential catastrophe waiting to happen? Started about a month ago.

I only replaced mine when it reached the stage of a big clunk when going from forward to reverse.

+1 diff.. i also replaced mine at the point of big clunk fwd to reverse, with an ashcroft replacement too...

the only thing i would say is that the ashcroft paint on the diff will last about 5 minutes once on the vehicle, so repaint with your favourite stuff before you bolt it on

i guess jmc will need someone state-side though

Ill be giving that job to a local LR guy. Just trying to get a feel as to how much this job should cost, ballpark....

When mine got to that stage I bought a S/H diff from a local wrecker with a “guarantee” that I could swap it for another if it wasn’t up to snuff. Replaced mine with it, very simple to do, no more whine.
