Hi Guys,
Hello to all .. my first query !!!
I've developed a rear whiney noise with a dry grindy sound to accompany it Confused, heres the breakdown:-
Disco 300 TDI Commercial with OME HD Lift of about 2.5" - 3", Springs: 764's and 763's, rear cranked arms from equippe, 33x12.50x15 BFG muds.
Sits quite high cos i have stripped the rear seating and carpets. Its had a rotoflex for the duration of the lift (6 months). I have jumped in the back and got the missus to drive the truck, holding me ear to the floor panel It sounds like the rear diff.
• Noise stronger on accel and when Cornering (left hand down louder)
• Reduction in noise whilst braking
• Noise still there when rear prop removed
• Checked a little bit of the diff oil without draining and looks like new
• No obvious play in wheel bearings or swivels when jacked and checked
From what i have searched on the net it sounds like pinion bearings or grooved crown wheel ?
I have a UJ to UJ prop which i will be fitting when i get to the bottom of the problems above.
Please help confirm my suspicions or advise on next steps of diagnosis ..
Thanks
TPK
