Howdy,

Noticed today that my LC100 IFS is sitting lower at lower left front than the right side. When measured from centre of hub to bottom of wheel arch left side is about 20mm less that right side.

I have also measured how much each shock is compressed, left one is compressed about 12mm more than the right.

Is parked on paved level driveway so no probs there.

Any tips...is it simply shocks or anywhere else I need to look?

Thanks

Brad

Whats in it at the time, the fuel tank is on the left side so maybe its full as that will add 90kg.

Anything in it as well Is the back down too or just the front.

Gday Graham,

Actually I have to admit I didnt measure the back as to the eye that looks okay however having just measured that it too is 20mm down so must be fuel. There is nothing else in the car, fuel about 3/4 main and sub is full which looking at that just is also slighly offset to left (LongRanger).

I know there is some weight in all that fuel but didnt think that would sag it so much but it must be that. I'll take a look at her once tanks are low.

A bit red faced..oops. I also did the old bounce which I never really liked but seems to be firm enough.

As noted below I will get under and have a good look around.....once it stops raining.

Cheers

Quick fix is to wind the torsion bar up a bit on the low side.How recently has it sagged? I would climb under & have a good look around the front suspension components as they are prone to cracking the lower arm around where the torsion bar connects on.

IMV, torsion bars and coils control the height. Shockers only know about 'movement' (in simple terms that is .... but I stand ready for a techno onslaught :-o(......... I had to tweak one of my torsions bars at one stage (05 model) - was only looking for about 10mm - all expected in my view from time to time, what with the mucking around with gear and setup etc. Re shock's.......mine had EMU's all round when I bought it, but I've now got Bilsteins front and TJM XGS rear. BTW - I jacked the front body up before tweaking the torsion bar adjuster - less load on the bar.

Brad

Darian is right - look at springs, not shocks. Try jacking up the torsion bar in the way he said and see if you can get it level and if so check it in a few months.

You need to see a 4WD specialist of suspension place if you cannot get it level.

Hi Max,

Thanks for the feedback.

As noted above also looking at fuel load......What do you think of that? I was surprised at that however I am carrying about 200l at the moment and both the LongRanger sub and main are offset to the left. The LR is at a rough guess about three inches off centre to the left.

That said I gather then I aim at setting it up so as it is level under a "normal" fuel load by making the adjustment to the torsion bar. Correct?

I usually have a good eye for spotting this stuff and have not noticed this under full fuel load previously.

Cheers

Hi Brad

The fuel tanks are around the back axle - I just can't imagine how a couple hundred kg in the back is going to deflect the front suspension by so much. The fact that you have not seen it before probably confirms that something has happened.

You do need to look pretty carefully to make sure nothing has broken or cracked, then I'd try jacking it up to level and watch it over a few weeks.

Its fun crawling under the car isn't it?

Yep thats what I came to also. First when it was mentioned I thought "Oh yeah that could be it" but then thinking over it it didnt add up.

As for crawling under cars......and its raining all day and the ol carport doesnt exactly stay dry....fun indeed. Hopefully it will dry up tomorrow and I can get stuck in.

Cheers

Hi Brad. If you do lift the torsion bar make sure to get the wheel alignment checked as it will probably upset the toe in and possibly camber/caster. Bob.

Not if you only jack it up to where it was/should be.

Are you sure it's not meant to be like that to compensate for "the average sized 4WDer" sitting in the driver's seat (RHS)? ;)

I assume the front wheels are pointing straight ahead and you've driven straight for a car length or so since making the last turn? Often your car won't sit dead level if you've just made a tight turn eg. to get into a parking space.

Possible, however as mentioned I have not noticed it previously. Yep is driven straight etc priot to parking and same result.

I was going to get stuck in and start making adjustments today however with 200kg of fuel I currently have on board I'll run that down and take it from there just to rule that out.

If anyone else has tips please feel free to post.

Thanks to everyone for their valued comments. And with no full on forum war starting. Good to see.

Cheers

Brad
