E240 Whiney Diff ??

[BENNYANDTHEJETS]

Hi
We just got another E240 , which had been stood a while, seems to have developed a bit of whine on over run and in drive, footbrake was very stiff & Tight ( Thought the rear pads may be ginding ? then thought wheel bearing, ( But had brand new mot unless they missed it,? Q: are the E class renowned for noisey diffs propshafts ect , or shall I just get my mechanic to check it out. Thanks in advance

Check the tyres firstly. Diffs on the 210's don't often whine.

thanks for that blackc55, but its not that kind of noise, brand new rear tyres ! its very transmissional or diff, but in hindsight may still just be the rear whell bearing singing a bit, we just just pray its not the auto box !!!, but we'll flush it next week and new oil anyway " Cheers"

Funnily enough, I've been trying to sort out what I think is a worn rear wheel bearing on my e220 recently,( been meaning to post up a pic of the driveshafts for Olly to look at but haven't had time) Anyhow, while the car was up in the air I thought I'd stick the winter wheels & tyres on. Lo and behold most of the noise I could hear before has disappeared. There's still a low rumble which is almost certainly a bearing but it's barely audible. The summer wheels are 17" alloys with Falkens 452's on, the winter wheels 15" steelies with Pirelli mud & snow tyres fitted. I'm not certain it's a wheel bearing making the noise now, it hardly changes pitch when cornering, maybe a diff or gearbox bearing, I've changed the propshaft bearing which made no difference.
