Hi, just been out in the car and the diff mount has gone , are they easy to replace ?

 

Are you sure it's the diff mount?

As mine has started banging around and I thought it was the diff mount but after checking it proper it's the rear beam pulled out the floor

 

ouch

 

Oh yea ouch indeed I really thought it was the mount as it knocks like the mount has gone

 

mounts fine, and its bracketed to the floor quite sturdily, just a shame that bit of the floor isn't attached to the rest of the floor anymore

 

That is true mate the mount is perfect and where it bolts to the floor is perfect

 

Just googled it and it is so common for it to happen always the ns mount aswell

Harris jack up the ns and have a good look at where the beam mounts to the floor I reckon that is your problem mate

 

If its a thudding noise under load, its the prop shaft donut and carrier bearing just after the gearbox. They are probe to going and the vibration travels throughout the car and makes you think its a diff mount.

Gen BMW bearing - £78 + vat
Gen BMW donut - £154 + vat

 

Maxwell mine is a thudding noise on and off load and it's the chassis mount

 

Ok. But the OP hasnt said under what circumstances his mount has apparently went.

I just merely pointed out that IF it was UNDER load, the above problem i mentioned may have occured!!

Happened with me. Convinced it was a diff mount, took it to AI Autosport and he showed me what it was. The donut and bearing carrier was replaced on the prop and it hasnt done it ever since!!

 

Hopefully that's all his is

Mine is a bastard lol

 

If the rear beam pulls out of the floor, its a breaker!! Financially not worth the hassle!

 

Yea I know but I for some stupid reason am going to try to fix it as I love the car I know there is millions of them for sale but I love this one lol

 

Horses for courses i suppose!!

 

On and off throttle it makes a constant knocking sound and the rear end don't feel to stable . from what I can see above its fooked

 

Have a good look at the passenger side mate see if it's gone there

 

Will do mate . just look at the bushes yeah?

 

Bmw quality lol.

 

Theres loads of videos on ebay about this. Here is just one of them.

 

Haha from the guy who spending thousands on rust! Been there done it

 

hahaha, and ppl say fords are rusty buckets. Not one of my fords have ever been rust at this point like the Beamer shit. Welcome to the german car build "quality" *cough* but all cars have their good and weak points, but this is critical IMO.

 

^ I'm Guessing that's an extreme case??

 

I'd say so, my E46 is mint inside the boot etc. I checked when doing the starter the other week. Seems a lot of M3 suffer bad is their any reason, more stress on the back end with greater power?

 

it was a big prob on all cars from this era, sometimes more, sometimes less.
There was a big recall here in Germany, if I'm right and after that they were solid at this point.

But BMW was clever, it seems that they send only the corrected cars to foreign countries to keep their "good" and overrated image of good cars
