IFS Hilux rake angle

[Pog]

Hey fella's,

To cut a long story short, my Lux sits lower in the back than the front (unloaded) and my short term solution is to wind the torsion bars down a bit as they are up excessively high. What I need to know is how much higher is the rear than the front normally? Measurements from hub to guard,or from designated points on the chassis (and the subsequent front-rear difference in height) would be fantastic if anyone has them!

To reitterate, this is only a short term solution. I will lift it sometime in the not so distant future once I have some spare cash. And yes I am aware I will need a wheel alignment!

Cheers,

Aidan

Do you have a duel cab or single cab?? I have a duely and i wound my torsion bars up at the front and they're still not the same height as the back!

I just did the quick check from the hub to the underside of the guard...

Still haven't had a wheel allignment :(

Don't waste time, do the alignment ASAP-

Home Wheel Alignment, to get you to a professional aligner without too much tyre scrub

Yes, this is real backyard stuff, but it will make the steering safer after the torsion bar adjustment or ball joint spacer install and will save your good tyres from damage for your next trip, to the wheel alignment place.

With the applicable wheel in the air, adjust the camber so the Camber Pin lobes are further inward from where they were before the Spacer install.
Both Camber Pins on both sides must be adjusted by the same amount. You will see reference marks in the Camber washers. A helpful thing is to get a paint pen or white correction fluid and mark all 4 before adjustment is made.

Now loosen the Camber pin nuts about 2 turns and adjust both camber pins bolts, by their heads, to correct the negative camber. This image is a guide only. You will need to use your eye or a vertical spirit level against the tyre sidewall, not including the bulge when weighted tyre is on the ground.

Be sure to re-tighten both Camber Pins on each side when finished.

Next thing is to adjust the Toe-in. Car is to be on the ground for this. This is done by loosening the 2 nut and bolt clamps, (marked with yellow X in the following picture), on each adjuster and rotating the adjuster, (with vise grips or stillsons), to increase the distance between the 2 Tie Rod Ends. Be sure your steering wheel is in the centre position before adjusting the front wheel Toe position to be tracking straight on both sides.

You can look back from the front wheel and compare the front wheels to the back wheels or use a string-line to get them close to straight in relation to the rear wheels.

Be sure to re-tighten both nut and bolt clamps on each side when finished.

Now move the vehicle about 20M and come back in a straight line and check the front wheels are near to straight and camber is OK.

Sorry, its a dual cab. You've got me thinking now that my rear springs are stuffed..

I wanted to say that, but didn't know the history of the car!

It's absolutely normal for the rear to sag with coil sprung car, like the Hilux Surf.

When it comes to 4 leaf sprung Hilux, the front usually sags, as the front spring go middle-up. The rears are always heavy load rated and don't usually sag.

When it come to IFS rear leaf Lux, I would agree with your suspicion.

Perhaps some leaves have been removed or heated to reduce tension to give it more flex off road. Or perhaps it's been carrying 1 tonne of stuff for all it's working life.

Well I guess the only way to find out is to measure it!!

In its past it has been onroad only 99% of the time. Not sure about carrying heavy loads, but it still had the original shocks when I got it so I doubt it.

[v6hilux]

The shocks don't really contribute to ride height, they just stop bounce.

Has the front suspension been modified, like the control arms down travel bump stops trimmed or Ball Joint Spacers added before a torsion bar wind-up?

I was more saying that if it had been used to transport heavy loads regularly, chances are the rear shocks (at the very least) would have been upgraded. And even so, carrying those sort of loads with a 2.7 petrol isn't exactly ideal!

And no, no front end mods with the exception of cranking up the bars.
