My 96 Club Cab 2500 2wd 5 Spd That I Just Bought Has A Strange Vibe While In 5th, When You Let Off The Throttle, Right Before You Let All The Way Out The Vibe Happens Same When You Accelerate. If You Accelerate Past That Spot In The Throttle Everything Seems Fine, Also When Taking Off From A Dead Stop Its Like Something Is Binding Because When I Take Off It Locked Up Then It Releases But It Doesnt Do This All The Time. One Other Thing Is When Im Barely Rolling I Get A Bumping Feeling From The Rear. Thanx, Any Help Is Greatly Appreciated!

 

For starters, have a good look at the u-joints. They can transmit some weird feelings when they seize or become loose. Possible too to be a broken tooth on the crown or pinion. Take the cover off the rear end and try to pry the carrier side-to-side. (truck in neutral with emer. brake on.) Make sure there's no end play to the carrier. Have a look at all the teeth. Remove the driveshaft and flex all the joints each direction.

 

I used to have a shutter when turning w/a load. Most auto parts stores sell a tube of "anti-shutter" fluid, you could try that, it worked for me..

 

rear ends dont usually vibrate when something is wrong, more of a noise issue. check the driveline u joints, pop the cover and check the spider gears also.

 

They can get HOT also when something is wrong. Warm is normal, but not HOT.

 

my rearend i guess went **** up? and the guy wanted $1400 to rebuild it he said everything was shot but i might be able to salvage the ring & pinion even the axles were bad. i havent looked at them yetthats just what i was told on the phone.

 

Check redlinear on Ebay, just was looking thru his store last night, he has 2 right now cheaper than your rebuild cost......

 

i bought one at the salvage for $500. dana 80 3:5 ratio with a 90 day warranty

 

Thats a pretty good deal I got 1 for 800 for my first gen
