blxxxdy squeak

me 200tdi disco has developed a intermittent squeak

first off it sounded like alternator bearing... i took the drive belt off , drive end bearing feels a bit rough so i ferreted about in the shed and found another that looks like it will fit on.... only problem is its pulley is bigger.... think theres enough adjustment to get it on but then me rev counter will read wrong cos of the bigger pulley... so decided to swap the pulleys.... funny thing is its a different shaft size.... so had to disturb the moths and buy another alternator..... cos both belts looked a bit past it i shelled out for new belts aswell..... steering and water pumps both feel fine.... put it all back together
no squeek for about 3 miles then its back again

though this squeak sounds engine related it never happens when stationary and usually goes away if i lift off the accelerator....so i crawls underneath today .... the back uj on the front prop is about to fall apart... so took the prop off ... guess id better stick the diff lock on and go for a drive to see if me squeak comes back... bloody heap dont move ... looks like the diff lock has decided to stop working aswell..... twas ok xmas before last when a cv joint went a mile down the road.

guess im stuck using the fourtrak till i get the prop done or find time to poke at the diff lock

I had a squeak once, glue board sorted it out but it did chew through a seat belt first. Maybe not relevant but thought I'd share

Penny trick?

stuck a new uj in the front prop this afternoon, squeak appears to have gone.. amazing what a difference a few little rollers and a bit of grease makes.

funny the one that went was the one without a grease nipple.

I've got a squeak at the moment which is driving me up the bloody wall. It isn't there 100% of the time, it comes and goes and really ruins the V8 soundtrack. Sounds like it's coming from the front left of the car but when I get under it nothing really shouts out at me as being awry.

This being said, I'm not yet all that knowledgeable about the different bits and bobs (which was one of the reasons I joined this site, so I could learn from people who do know what they're on about)

Does anyone have any ideas?

Cheers,

When mine was squeaking a lot last summer it turned out to be one of the front brake pads. The friction material had separated from the metal backing. New pads made it a lot quieter. It wasn't a continuous squeak, but came and went at odd intervals.

If it doesn't move with front prop off and in diff lock are you sure you haven't got a half shaft gone in the rear axle?
