A silly thought, but all your tyre pressures are correct ?

AFAIK all/most Patrols tend to pull to the left....they were not designed for our left-road driving, camber etc. Try driving on the wrong side of the road (eg: when overtaking) on a quiet country road (Please be careful; I won't accept any responsibility for you having a head-on bingle!!!! hahaha).

I have fitted a 4Ways Return To Centre steering damper and this has helped my GU a lot.

Cheers

My last GU (3litre) was a bugger pulling to the left. Fitted a 4Ways RTC and the problem became only slight. Changed tyres from Cooper A/T's to BFG A/T's and it ran pretty true. I'd suggest an RTC as Roachie said.

Hi ,
I dont know anybody thats got a Patrol and doesn't pull to the left , allbeit even slightly, it's a common fault with them,there is one solution and thats to have a castor correction plate fitted , dont know how much that would cost but I ended up just living with it as it didn't do it all the time, also heard mags would help,
anyway finally solved it.................by selling the Patrol...............
sorry couldn't resist that,
regards,
Dave

Mine does the same thing and I have learned to live with it as well, I don't think there is anything you can do about that

Mine did the same, I fitted castor bushes to the left hand side. You need about 1/2 to 1 degree extra caster on the left side to allow for the road camber when driving on the left side of the road, patrols and many other vehicles are set up for other countries and the castor was about equal on both sides. I did the bushes on mine rather than the plates mainly for the cost, about $130. I fitted a return to center steering damper before doing the bushes and it almost took the pull away, but the left hand front tyre started to scrub on the outside edge.

Geez DJPatrol!
My 2001 GU did NOT pull to either side, so I wonder about others' comments that they all do. These other guys probably have more experience with Patrols specifically, but if yours is becoming worse, then clearly there is a problem, and it is not normal ex-factory stuff.

I would check things like brakes. Calipers can seize at times, pistons become a bit sticky. Wheel bearings (LHS?). Jack the wheels up and check lateral play and resistance to rotating. Easier to compare if both wheels are in the air at once. Also check for worn steering knuckle bearings (king pins equivalent). Grab the wheel top and bottom and try to rock it hard. Or both hands on top and rock hard, to feel for play. Steering joint play. Have somebody rock the steering wheel back & forth continuously while you check for play at all steering joints.

Also, even though tyre pressures are even, there could be problems if tyre wear is uneven.

You could swap tyres front to rear &/or side to side to see if there is any influence. May be other things I haven't thought of at the moment, but hopefully it's not too hard to find.

Hope you have some luck.

Regards
Brid

Hi djpatrol,

Agree with Roachie and Craig, put a 4ways RTC damper on and put slightly more pressure on the spring when setting it up, worked well with mine.
Also as Peter said try lowering your pressures, I run 36 front and 34 rear when empty, smooths out the ride a bit and less work for your shockies.

If you want a quality lasting solution to your problem take your rig to a Big Wheels Truck Alighnment centre they have branches in every major East coast city.
I had the same problem with a Dana 44 on a 4x4 F truck, had about four alighments in the space of 18 mths from so called alighnment specialists all amounting to zip, Big Wheels took most of the day to do the job but they got it right, they actually tune the suspension to the vehicle, sometimes setting the suspension to manafactures specs just won`t cure the problem (gotta think outside the square) cost me a bit over $400.....spittin that I didn`t find em first up.

My GU pulled to the left and got worse over time. Went to 3 or 4 so called specialists and they all said it's within specs and there is nothing more that can be done. Then I went to a bloke who does aglinments on trucks and he said he could fix it. He did almost. It still pulls slightly to the left but only when there is a fair camber on the road. On freeways etc it is near perfect. Not as good as a ford but the nissan is a japanese light truck and will always ride rough.

Forgot to say he reckoned the LHS wheel base length was shorter than the RHS, or the oher way around. Anyhow that was about 120,000kms ago and I have done nothing to that part of the vehicle since (the rest has been rebuilt!). He reckons he'd done heaps and not just nissans and he could have fitted a castor correction kit but then I'd be pulling to the right.

Apparently Nissan do have a 'fix' for this - have seen it mentioned on other forums but apparently the guy who had it done says that his Patrol now pulls to the right!! Just cant win!!
