Tire pressure affecting driveshaft?

[tarheels23]

I've noticed that when im driving and and I let off the gas I swear I can hear my drive shaft rotating like its out of balance because my tire pressure affecting the level of the car. I have my fronts at 29-30 and the rears are around 32 like the manual says. When my rear tire pressure is lower The drive shaft noise isn't there as much. I don't want to drive around with a lower tire pressure because my rears are wearing pretty bad on the outsides because they like to randomly go flat.

what can I do?

You can replace the worn ujoints, carrier bearing, and/or carrier bushings.

I would have to check, but I am almost certain you have your pressures backwards. That being said I seriously doubt 3 psi is going to throw off the driveline enough to affect anything. Most likely you have a bearing going bad.

alright thanks for the replies guys! Ill look into my u joints and then move on up. I had even filled my carrier bearing with black silicone when i did my transmission and it worked for a few months

You should put the tire pressure at what the tire is rated for not what some manual says to put it at, although 32psi isnt bad for it and 29-30 is a little low. I put mine between 32-35psi.
