Hi everyone

Im very frustrated dont know what to do need help

the other day I tried to fix a vibration problem it felt like it was coming from the drive shaft so I took it out and replaced the u joints on both ends I tapped them in.

I spent about 2 hours trying to line up the bolts to the metal mounting cover. After I got the car back together I drove it and started making a noise as I shifted in each gear Park Reverse Drive.

I took it back apart and read in on line that the mounting cover bolts would cause damage it overtightened so I loosened them up a little.

Put car back together and it now makes a noise seems like its comming from the front of the drive shaft it almost sound like its rubbing against something.

The vibration is worst then before can anyone give me a fix

Vibration Question the only other part of the car that I worked on was the front of engine I had taken off the front crankshaft pulley to put in a distributor. Do you have to set the engine to top dead center on #1 pistion on a 1994 C4 also does the crankshaft pulley have to aliened.

The vibration starts when on highway going about 20 to 50 mph if you stomp on the gas it will go away. If I put the car in netrual it stops as well

Thanks

 

Sounds like something is loose in the driveshaft, that would explain the noise. Was the vibration there before the balancer was removed?

 

I dont think so can you give me some steps to find the problem

 

Check that the bolts that hold the u-joint retainers to the yokes are tight and the u-joints are centered in the yokes. If you're getting a clunking noise when you put it in gear, that's usually means something is loose.
