Whirring noise

[John Laidlaw]

Right, back to the tyres! Whilst those Chinese tyres might be ok in a complete set (and I use the word “ok” with caution), on the rears they are quite likely to fight against your front Conti’s which are a more modern tread design. I’d be looking to ditch those before they ditch you , fairly certain that will be either your mystery noise too.....or at the least give you an interesting handling characteristic come winter.

Cheng-sheng-slimes have no place on a Mercedes. Shows a worrying lack of maintenance care (to me) by previous owner.

Sorry this is the correct one

Maybe I should try myself, what about gaskets?

I totally agree I would never put tyres like that on a Mercedes or any “performance/luxury” vehicle.

I put my foot down yesterday, not hard just to over take a 40mph driver in a 60 zone... yes the back end slipped out.. nippy bum moment!

Out of curiosity mind... how much do you think a roof set of roof and boot seals would cost to buy and get fitted LOL or do I not want the answer

 

[Richie Livo]

And should these seals fit flush?

Plenty on YouTube , or Haynes manual . Two big threaded plugs , one for fill , one for empty . Refill until it runs out of the fill plug .
Not for me to say if you should start DIY'ing , I don't know your background

Should just be a copper washer on the diff drain plug so its reusable. It is on mine anyway, took me an hour to do from drain to refill! 20 quid ish for the oil. Possibly Mercedes recommend to replace the plug but I didn't bother myself!

Make sure you undo the fill plug BEFORE undoing the drain plug.....

Otherwise you have to turn the car upside down to use the drain plug

Thanks guys! Other thoughts on my previous questions regarding seals ? ^
