Was heading into town this evening in my 1990 Mini 998cc when a very loud rattle started from under the front of the car :evil: ...not an engine rattle, it sounded like 1 of the front wheels was lose and about to fall off. Pulled the car over and both front wheels where tight, track rod ends and balls joints all look good.

Do they give drive shaft trouble or could it be something in the gearbox or maybe it's something totally different...any idea's what it might be :?:

Thanks

Jim :(

maybe your engine steadies need replacing, could be you exhaust rattling off the bottom of the bulkhead?
also could be a shock mounting, up under the front wings, grab the top of the shock and give it a good shake, any play and they might be the culprit

Thanks Macker

Will check engine steadies and shock mountings, deffo not the exhaust.

Is it normal when you grab the inner joint on the drive shaft that it feels lose in the gearbox...it will sortta rock if that makes sense :?:

Thanks

No stones in the dust sheilds.

Car has to be moving for it to make noise.

Got the car up in the air earlier today and noticed a nice bit of oil coming from the R/H driveshaft oil seal and there seems to be alot of movement in the shaft...do Minis give driveshaft trouble or can something happen in the gearbox that might cause the shaft to rock so much :?:

I have the same problem i think. It is coming from behind the passenger side front wheel. Its just a rattle i would imagine something is loose around the brake housing or something. I have been meaning to jack it up and have a look. When i do ill tell you what mine is.

The inner CV should be tight, it sits in a bush in the diff housing and is not something that goes suddenly. Is the noise ther constantly? .Have you tried jacking the wheels and driving them slowly?

Hey Woody,

Thanks for giving me a shout...

Jacked the front of the car up this evening and it's all quiet but once the car is on the ground driving it's making a hell of a rack :twisted:

It's now stuck in the air with the 2 drive shafts out of it and there's alot of play in the shaft that the drive shaft slides onto in the diff, especially the drivers side 1...What does that tell ya :?:

Cheers

Sounds like the diff, unfortunitly its an engine out job so if your not sure get a second opinion.
