Ive got a 98 ram 4x4. I was driving home and at a stop light. I accelorated hard and felt a hard vibrating grinding rubbing noice from the front driver side of the truck. It only does it when i accelorate hard. any other driving there arent any noices. Any ideas

 

First off, welcome to DF.

Take a look at your u-joints and see if there is any play in them.

 

best would be to jack up the front end and in neutral rotate the tire, it should spin fairly freely, if not its probably the bearing. take your wheel off and check the brake rotor, sometimes little rocks and debris will get in there and make wierd sounds as well.

 

Its not the u joints. and i spun the wheel and moved it and its not bearings. I cant go into 4x4 now and when it binds up the shifter on the column is extremly difficult to move

 

and the tranfer case and tranny were recently rebuilt. I dont understand why its only during a hard acceloration from stop. it sounds like something is grinding and bounding up until i let off the throttle

 

I think we had another member with the same problem.... his issue was a range fork contacting other moving parts in the t-case.......

 

that would explain why because i cant even move the shifter to 4L

 

is it adjustable?

 

I am thinkin' if that is indeed the problem........ then the t-case needs to come out, and rebuilt.

 

If it's not too late a Transfer Case Saver might help. Pull the rear drive shaft and see if the output shaft moves in and out an excessive amount.
