Can anyone advise on what could be the cause of my 4.2 lt diesel DX Patrol wagon vibrating at low speed.
It is really bad at 1000 -1200rpm in 1st or 2nd gear vibrates the whole cabin and drones really bad,you can feel it right through the drive chain.
At higher speeds it is fine.
Any ideas ?

Gearbox bearings, delaminating tire, hole in exhaust, clutch bearing dodgey Universal joint..
Lots and lots of different things. Best get it checked early, incase it dies when you dont want it to.

Peter, Relax and get used to it as it is uncureable. My mate has the same truck with the same problem and has tried everything and I mean everything and finally contacted Nissan. They said that even they didnt know what the problem was but closed the book on it as they were releasing the GU model. Contact him at darryltownsend@bigpond.com.au if you would like it from the horses mouth. I avoided the problem completely by buying a TOYOTA! Good luck.

Peter, sounds like the typical growl that comes from most GQs. My mate's has been doing it for years - about 300,000 kms and not ,causing him any problems. I must admit that some I have heard are worse than others.
Happy cammping!

Peter, We found this in both of the 4.2 diesel Mavericks we have had over the years. This occurred from new in our first Maverick and we have just bought a secondhand Maverick with 250,000 klms and it does the same thing. It seems to be a symptom of the gearing within the diesel drive train, in low revs and gear ratios. Will probaly find in most diesel run trucks , tractors etc this is a common occurence. Geoff

Peter, how long have you had the car? Sounds like you're a recent owner because mine's been growly since new ( '92 Mav ) and is still the same now at 192000Km. I hit the panic button originally and asked workmate GQ owner/diesel mechanic who said don't worry. His and all others he knew of were the same. Sure sounds unnerving at first but remember it is a truck transmission. Reminds me of old Mack trucks I once drove on a salt pond years ago.They were just about bulletproof too! Have faith and relax.

Peter,
My GQ diesel does it aswell. It drives me crazy, especially when going offroad over rocks etc at low engine speeds under load. Suprisingly I drove a 1988 diesel one the other day and it didn't do it at all. The owner informed me that it had a new clutch fitted before he bought it. I wonder if maybe the genuine clutch is the problem. The vehicle had 340000km on it.
