Outer Limits 4x4 Board

Mate's got a 100 series with a vibration problem. Not your normal suspension/steering component problem?

He's checked all bushes, bearings, etc. and can't find a problem. Jacked it up with all 4 wheels off the ground and problem appeared to be coming from front diff. Took centre out and had diff specialist inspect it. No problem, got new bearing kit put through front diff anyway. Still problem.

He reckons it seems to be a body vibration. Body mounts all tight.

Any suggestions, is this a common 100series fault?

Can anyone suggest a GOOD 4wd mechanic who may be able to nut out this problem, he's in Point Cook. I suggested OnTrack. He's a mechanic himself (nissan dealer about 10yrs ago) but its got him fukd.

Does it only kick in at speed? Someone could have taken the drive shaft out and put it on wrong. Mine has a vibration at 100 when i back off the accelerator. I checked diff centre, bearings, rims and tyres the lot. Turned out to be in my transfer gears (automatic). Too much hard driving.

If it is the same as the older 95 series Prado's used to get he's got the landcruiser boom....

Can you elaborate on this. I'm a Nissan man

Hard to elaborate. I have no idea what causes it so can't help rectify it but whenever we trade cruiser or prado we always drive them. Some of them just have a boom in them like the whole body in vibrating and it comes through the whole car. Pretty hard to sell one that boom's so they usually go to auction or sold to other yards etc.

Pretty common in my experience. Never heard of it other makes. Might be because they are AWD? Only usually in cars done 200+ks.
