Drive Line Vibration - Infamous Nissan

mcbeaven · 05-04-2014, 10:05 PM

Hey everyone, I just bought a 89 King Cab 4x4 5speed SE 135k kms (80k miles), super clean truck, everything works, pretty excited. However there is a vibration that comes on under heavier acceleration/load mostly in second gear at 3k rpm. When I push in the clutch and rev the engine, no vibration. I also notice when reversing and then going forward I can feel and some what hear the rear axle moving around. In addition the shocks are shot. Ive grabbed the driveshaft, doesn't slop around so im guessing its not CV joints? The truck tracks well and is quiet on the highway, no vibrations. Also the truck doesnt look to be sagging in the rear end.

Are there bushings in the leafs where they attach to the frame? could they be worn? is it that my shocks are allowing the rear axel to move around? Are my leafs gone?

Thanks for your thoughts
Cheers

Check the carrier bearing in the middle of your drive driveshaft its between the transmission and your rear differential. It may be worn out and need replacing.

2nd on the carrier bearing.

Can I just grab the driveshaft with my hand and check for play? or do i need to remove the driveshaft?

So im still unsure of how to check this carrier bearing, the drive shaft is free of play.. Also when reversing then changing direction there is an audible clunk from the rear end and it feels like the rear axle is rotating..

As far as visible signs the rubber will be worn/torn and you can kinda shake it at the bearing up and down side to side movement, but it definitely sound like youre having the same issue as me. I have a new bearing I've just been lazy to do it. Mine although vibrates on the Highway at 65+ and makes a semi rattle noise almost.

you can remove it and check your u-joints. there should be no stiff movement if so. it needs to get serviced. or replaced

Worn Carrier bearing, drive-shaft yokes out of phase. Is the exhaust touching the frame. Worn motor mount(s)? I’m not at the computer, I can upload a diagram of the yokes in phase thing when I get home if someone doesn’t beat me to it.
