like to no if my diff is on its way out

Firstly welcome..

What problems are you experiencing?

thanks lad if i go over 40 there is alot of judder under the back of the car

Typical is a 'Whining' noise at speed.

More serious problems have different symptoms so we need more info. Is this judder physical? as in... causes vibration?

Bearings or bushes? More likely wheel bearings dude.

Get the ass of the car in the air, firmly grab the wheel/tyre and give it a good rattle. If it has 'give' or makes a knocking noise, It's ganna be what The Gavman suggested

Keep us posted on your findings

but also + 2 as gav and daz says.......if you do that and find nothing then take the car to a tyre place and get them to check wheels.

I had a Volvo T5 with 18" after market alloys, bought it off some bloke, who told me there is a slight vibration over 60, think tracking is out...sure when i drove her home i went over 60 and could feel my teeth rattle it was that bad but even when i went upto 90 the vibration just got worse, took it to my mates tyre shop to get it tracked and balanced all round, as he was doing it he came out and said the rear wheel was so buckled that he couldnt balance it out.I ended up buying a new set of alloys cause a week later the missus was driving the car and hit a great big pothole and buckled the 2 alloys o the other side. so Just another idea but do also agree with Daz and Gav.

hi lads thanks for all the info this is to DazH there is alot ov vibration when i go over

40 mph its peeing me off

Vibration will be the Prop centre-bearing that has worn... Or a mis-balanced drive-shaft... ;)
