Funny thing I adjusted my rear brakes a week or so ago and didn't take the hubs off to blow any dust out (being lazy=$ as I know now) and one grabbed and locked after a short test drive...
Seems that's all a 260'000k stock L.S.D diff needs to form "what I believe" is a diff/clutch shudder (x2 diff oil changes, no change) ... I will have to do the dreaded 1st 2nd on the stands to be sure, it may be a centre bearing also as I just installed leafs and bushes, air bags h/d clutch kit thr/bearing spigot etc, fr/diff out sump off clean and re seal and replace rear main.. Hey that liquid moly flush is amazing shite indeed..
Sooo I'm thinking diff centre replacement "the eaton e because of the yanky dollar is now $1'600'- danmit!
Tell the truth I don't want to add lines "air or power" but I would rather a 12v switch over air..
..what else is there? I'd like to go detriot but am I right in writing that they don't do any thing for the Nav'...d22
