Slight vibration
Hi guys. I'm getting a slight vibration from the Patrol when accelerating, mostly at lower revs. I suspect it's the u-joints, but weirdly enough I feel it in the gas pedal. Going to check the joints later when I get home. I am also suspicious about the transmission brake as some weeks ago, I pulled it up in the traffic and got nothing. Seems the cable broke. Maybe it's rubbing on the driveshaft. Any ideas?

I havenpt jacked it up yet. I did check the shaft for play by the u joints. How do I check it for weights? If any are missing, how do I get them on a rebalance the shaft?

Is it a vibration or rather a kinda grunting you here on low revs around 1500rpm-1800rpm range(petrol engine) on 1st or 2nd gear during take off? Do you feel like the the "vibration" comes from clutch/transmission area(assuming it's manual transmission).

I feel the vibration in the body of the car mostly at lower revs when accelerating. On the highway I am also feeling it in 4th.

Ok, that may be or may not be the same thing.
The low rev grunting of the gearbox is fairly common in GQ Patrols.
I experience that in gears up to the third, though I can't remember hearing it on fourth and above though.
If the car body vibrates with that thing, then you may have something different related to pretty much anything in the
drive train, as well as suspension issues.

After driving the vehicle today, I realized that the vibrations were mostly felt at high revs. They seemed to have been getting worse. anyway, checked underneath this evening. Found that the bolts connecting the driveshaft to the rear diff were loose enough to be turned by hand. Going to tighten them up in a while.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.
