Title: Help! Wobbly defender 90
Post by: Cassillis on February 09, 2006, 20:49:29: Evening all :wink:
The blue pig, a defender 90 1996 300tdi tin-top with 104,000mls, has developed a distinct vibration through the whole cab at 40mph along with a squeal whilst pulling away. The sound is rotational, if you understand what I mean, and seems to be central. My man in the know seems to think itÃ¢â‚¬â„¢s the UJ at the gearbox end of the front prop shaft that is worn and causing this. Do you agree? Can I buy a UJ or should I replace the whole front prop shaft? Any help or comments would be appreciated.

If the prop is OK then just replace the UJ, get a good quality one tho, Hardy Spicers are good, and not expensive!
HTH

Ive just had one go, which started as a squeal when setting off, then developed into a shiatsu back massage at 50mph.
New one only lasted 3 weeks before I destroyed it on the rock crawl at Frickley.

They are straightforeward to fit, to check, chock the wheels, h/brake off, car in neutral. Get underneath and holding the end of the propshaft next to the joint try to waggle it up down/side to side.
If theres ANY noticeable movement, its a gonner.
Repeat on all 4 UJ's
Replace the joints that are bad.

Ive just bought a Landy joint as a spare, theyre about a fiver each.
While you are under the car, measure the diameter of the UJ bearing caps, and the width of the UJ(across the flats of the bearing caps) There are 2 Landy size joints used, and you can bet they'll ask you the size.
Saves going back under the car doesnt it... :D

Needed a new prop at Ã‚Â£100 or so to fix it....
