Discovery 3 ...

Hello all I have a question if someone could kindly help me please .. I have a disco 3 auto I have just had the back arms done on it and two new bushes plus two tires on the back I have also converted it from air to springs .. the gearbox works as it should and changes as it should and drives fine . The problem I am getting now is a lot of vibration and a sound like a tin can now and again it only does this at low speed and going around corners . I have been told it could be the new tires but I'm sure it's not ( if the were off road tires I could understand but their not ) I checked the drive shaft as much as I could and I cant find anything wrong with it as it doesn't seem loose . Would it be the drive shaft bearing ? also like I say I get the sound of a tin can as if It was banging against something .. Any help would be thankful .. cheers

If it’s just a tinny scraping sound it could be something as simple as the brake disc shields rubbing on the disc. also check the aluminium shield over the rear prop as that can rub against prop if it’s got bent when people have worked under the car. if it’s more a grumbling noise it could be wheel bearings or diff.
did you have the alignment done after changing suspension and rear arms?
As that could contribute to tyre wear and strange noises

Swap tyres front to back, see if noise/vibes moves or stays the same?

Hi Johnlad … Thank you for your reply … Yes I had the alignment done when the suspension and rear arms were done also it need two new bushes when they done the arms .. I will have and look at the aluminium shields because now that you say that that's what the tin noise sounds like.. When the rear arm went it also did in the new tires which I had put on around 3 months before hand so I have had to get new ones on now .. If it is the wheel bearings then I suppose it's not too bad but if its the diff then that's a whole lot of trouble and a lot of pennies I suppose .. I is a good truck it would be a shame to have to get rid because of the back diff ..

I have not done them, but apparently rear bearings are an arse job?

Think that’s cos the rear brakes have to come off. If you can do the brakes the bearings straight forward.

Is there a way of finding out if it is the bearings ..I would have thought when they fitted the arm they would have known the bearing had gone when they took the wheel off .. just my thoughts ..

Good to know, as my rear backplates are paper thin, and I have been avoiding the job!

Modern cassete bearings are funny old things, they can have zero play, yet be as noisy as buggery.

Hi I have a problem with my disco3 can anyone help because I had no idea of finding out . The problem is when I take a sharp righthand bend the car seems to want to slowdown for a second no lights come on on the dash such as warning lights . This only happens now and again and I think it's coming from the rear end would this be a bearing or the drive shaft .. Any help would be grateful .. Thanks

Could be the steering angle sensor needing calibration, if its out of whack it can apply the abs mid corner
