Side Lean

[2much]

Hi all, just noticed the other day that the Bighorn leans over on the drivers side. The difference is about 40mm to the the other side, is this just a case of adjusting the torsion bars or is there something else i should look at as well. Looks like the torson bar hasn't being fiddled with since leaving the factory as the adjusting nuts are still sealed to the mount with the original underbody paint/seal.

What year is yours as they do sag over time but also make sure that the tyre pressures and size are the same and also make sure that nothing is binding in the suspension by bounceing each corner It will be obvious if theres a problem. To adjust the front suspension take the wieght off the wheel first by jacking as otherwise you are lifting the weight on the adjusting nut + leverage 1 turn = 25 mm roughly Also disconect the sway bar before doing a final measurement I know of an Auckland Isuzu driver who spent weeks chasing a problem with handling The torsion bars were set very differantly but the sway bar still made the car leval.

Thanks for the reply Greeves. Yes I had bounced each corner to check if shocks ok and for binding. Its a 1994 bighorn lwb. I had measured from ground at each tire contact point to top of tire then to top of wheel arch, there is little diff in tire dia apart from the rear tires wearing out more so on there outside rim (even wear patterns on both sides of the isuzu)
Do I unbolt the sway bar first b4 jacking front end up and I assume there is no load on the sway bar!.
If the torson bar ajustments don't level things out does that mean its getting near time for new Springs or something?

There shouldnt be any load on the torsion bar at rest Some serious 4wders take it out completly But it can affect the springs if they are set differently So do unbolt the sway bar first with the wheels on the ground but be carfull incase there is load on it. As a rough guide aim to have the lower arm half way between the bump stops by adjusting it a bit then checking It is easier to adjust with the weight off the front but can be done without jacking but it is hard work. I would lift it turn the bolt about a turn drop it then check and repaet as nesecsary to get it right.
good luck

An easy way to check the heights is to measure form the top of your rim, to the top of the guard. That way it eliminates the tires! Goodluck! Still get it on level ground and make sure the tyres are inflated correctly, but thats just to ensure the truck is sitting as good as it will get!

Adjusted it Queens birthday weekend. Did as Greeves mentioned above and all went well, thanks. Bit of 'nutcracker' a week & night b4 to loosen up the bolts, but still the 17mm bolts at the front bracket for the torson bar where buggers to loosen...a bfh helped!. Had to loosen these bolts as well so i could move back the lever arm 1 tooth on the spline for more ajustment...the torson bar had already been factory set with very little extra for cranking up. The 1 1/16" (27mm) bolt was very easy to adjust with the bighorn jacked up.
The anti roll bars were not loaded when disconnected with the bighorn on the deck and it popped straight back in after cranking up the torson bar.
