Reaching out for a bit of help
Ive rebuilt my 4x4 saff from the ground up. Its had everything replaced / refurbished. from the minute i put it on the road, its had a vibtration / droning noise which comes on pretty much bang on 50mph, gets less but still there 60mph onwards. I at first suspected front bearings, even though they were new, so i got hold of 2 different front knuckles / hubs and fitted with SKF bearings. made no difference.

Ive tried, different wheels (all 4), diffrent propshaft, different rear diff. bearings as above, and nothing has worked.

the only thing i put back on the car that i didnt touch was the gearbox.
Anyone had anything similar on a 4x4 saff ???
