Thread: D3 - High-pitched whine, rear diff

What you describe sounds like wheel bearings. Wheel bearings can be very tight to the feel but still make an annoying sound, I have one on my garage floor that was making some sound, to inspection of all kinds it appeared fine, but taken out and spun it is clear that it was a problem.

Also, glad to be able to hear my new exhaust properly finally, so nice ...

Thanks, Epic. I will look into the wheels then. Did you put on a standard exhaust or a louder one? That V8 note must be pretty sweet, especially sans whine.

I came very close to unleashing my inner bogan (with a us sourced magnaflow system) but got cold feet because I didn't want to upset my quiet cruising cabin ! So I had a genuine LR one fitted (and it was a lot cheaper). Sounds pretty nice, most of the sound is engine noise rather than exhaust (it's a very nice sounding motor - very different to rover or chev V8's I've had in the past).

And good luck - hope you can get that sorted out those kinds of noises drive me nuts !

Out of interest, how many km's on the vehicle and what year ?

I wondering the same thing about both your vehicles.

Mine is March 2005 built (ie one of the first built D3s), 143,000km, owner with OCD so some of my issues are proactive fixes ... !

MY2006 Update (so built in '05) HSE with 220k. The previous owner was very fussy and the car was well looked after.

I picked up my 110 from the mechanic this morning. Up on the hoist was a D3 HSE. Apart from being filthy, it looked in great shape. I was surprised it was an 05 with 340,000 km. Auto hadn't been done nor had timing belt. I was pretty impressed.

Hi guys,

Yep - diff number four (rear e diff) was put in yesterday. I have now had two sets since I bought it earlier this year. The dealer finally agreed to put a new one in after putting in some pretty worn second hand replacements. I now have a late model second hand front diff and a new rear (with a new actuator).

The car is now quiet for the first time.... wow!!!

To put it in perspective, my folks 98 100 series petrol, which has done over 400k, was quieter!

Pretty happy this whole saga is over (touching wood).

Good work James ! That was quite an ordeal
