Ok so i have read and read about this but kinda confused here.
91, AW4, NP231, 8.25 rear, 4.5 RC LA kit, IRO H-n-T W/ front shaft (4.5* shims)
Ok so i've had the lift and H-n-T installed for about 3 mo. with very min. vibs at Hwy speeds 60-65. To the point i wasn't worried about it. I've been out a few times to get things flexing and settled in and all was fine in tell last weekend. I notice on my way home it was a little worse. Vibes happen while on the gas and worse while off gas/coasting. So i hit the search function. My output shaft is 7*, DS is 15*, Pinion is 12* so i'm 3* lower than DS. I know some will ask " how do you know its rear DL vibes"?
I've been running a week with NO front DS and vibs are getting worse.
Checked ujoints-seem to be good.
Put front shaft to rear. (actually got a little worse) Front shaft is 19 yrs old. LOL
Pulled rear DS, installed front and drove in 4H. Vibes gone other than my hubs that need to be replaced. LOL
So even with a SYE and a crossmember that acts as a T-case drop do i still want 1-2* below DS? Can i get a 5* or 5.5* shim?
Thanks!
