Weird Sagging on 4" Lift GU Ute, NEED HELP!!!

hey guys can any of you figure out whats wrong with my patrol its got me and both 4wd shops in town f*cked.

i fitted a 4" lift to my ute about 3-4 weeks ago was all good looked level and everything. Now heres where the problems start, i noticed that the driver side has dropped the other week. So lastweek i got the tape out and its dropped 35mm. Seems a bit too much for it to settle and seems a bit odd for it to be the one side. Ive only been out wheeling 3 times since ive had the lift in and it hasnt been extreme. first 2 times were mud runs and the 3rd time was just a sunday cruise out to one of the coastal parks.

Today i thought id give a crack and try and fix the bloody thing with no joy and it still sags. Heres what i tried anyway...

SCENARIO 1:
i swapped over the front coils to see if it was the one coil that was causing all the dramas so in theory the passenger side should have dropped. No Joy was still sagging 35mm on drivers side.

SCENARIO 2:
the guys up the road had a pair of 5" tough dog coils BRAND NEW. I put them in still no joy, went up another inch over all but was still down 35mm on driver side.

SCENARIO 3:
thought i give a go at swapping the rear coils over, so did that and still nothing.

now this has got me f*ucked! we took a few measurements etc and it seemed normal apart from driver side. had a look at the coil housings and none of them appeared to be cracked or bent.

Now has anyone else got any ideas? I got the coils through Snake Racing and they are the megalift ones. Its even got Ryno f*cked.

The ute hasnt got duel batteries or a winch either. Just has the standard steel winch bar that Nissan uses.

Before anyone asks i fitted the lift myself at work and the coils are in the correct positions.

might seem silly but it could be a bent shock . i had a bent one on the back that would cycle but would bind on the way in cousing the patrol to lean to the other side.
hope this helps :D

When you first installed your springs, you said it all looked level. Did you actually take measurements?

1. Try disconecting your panhard rod front and rear, then take measurements. You may need to buy adjustable ones.

or

2. Measure from the chassis to the ground. If it's level (plus or minus 8mm) it has to be anything above the chassis not the springs, ie. body mounts or body, etc.

ive got adjustable panhards but i cant see why thats doing it. had the front one out when i was changing the front coils and didnt make a difference. made a few measurments for ground to chassis and the most it was out was about 10mm, checked body mounts and that havnt punched through the cab. the tray and cab are on the lean.

yeah mate i had the same thing happen on tuesday fitted 4-5'' dobinsons
was 40 mm lower on the drivers side it was the panhard rod take the rear off and push it from side to side you will soon see how it effects it .. and dont forget to put the longer coils back on the right side ..

PROBLEM..... you have a sag on one side of 35mm

If the chassis to the ground is out by only 10mm...that can be fixed by a 10mm spring spacer.. THAT leaves 25mm


25mm lean is in the body or mounts.... Theoretically it can't be anything else... . ...HHHMMM INTERESTING ;)

undo and retighten all the bolts on the car suspension(should be done when doing a lift anyway) front and rear including draglink (front one) and panhards.
do you still have swaybars? if so undo them on the chassis end (this can pull the car down)

take out your shocks and check them aswell.

if none of that got me screwed

Has anybody thought about the extra weight on one side.

I had this same problem with my GU wagon. I was using King sp4 springs. It turned out that the GU is a bit heavier on the right hand side compared to the GQ and the sp4 springs were designed for the GQ.

I fitted a 30mm coil spacer in the right hand rear and a 5mm in the right hand front and the problem was solved.

I later fitted a set of King sp3 springs to my current GU and I had the same problem. I installed the same size spacers and the problem was solved once again.

hey mate i see what you mean, i took the rear panhard rod out the other day and moved the back end side to side and pushing it across to the passenger side it started to level up the front end. how did you go about fixing it in the end? did winding out the rod level it up more?
