axle noise

[pjsblazer]

I,ve got kinda of a womp-womp-womp sound at 65 and faster,78 K5 12bolt rear,203 case, already replaced frt& rear drivshfts,new mts frt&rear,changing tires didn't make a difference. someone told me,might be a pinion bearing.any ideas?

Could be , it won't hurt to check it. Grab the yoke and see if there is any play, mine was loose once after I sourced my 12 bolt, had to tighten it up only. Now of course just replacing shafts etc like you mentioned won't make any difference if the angles are wrong. Does this have any lift? /forums/images/graemlins/k5.gif

A womp womp womp sounds to me like a tire problem, especially at higher speeds.

Thanks, I'll check the yoke this morning. trucks not lifted,yet. I've swapped tires a couble of times. even putting on P235/75-15 street tires,didn't change.I know the noise is kinda hard to explain in print. this as been driving me crazy for about a year, now the t-case shifter is buzzing at the same time the noise kicks in.
