Level Suspension

[M35A2]

After spending 3 hrs yesterday and half an hour today on leveling my suspension, it is now set bang on to the factory ride height. Toyota says that this has to be done before getting the caster/camber/toe in and out done. They say the ride height has to be set to the factory setting so that the values they give for the tracking and caster/camber will be correct. They don't apply for different ride heights.

So it's all set now to go in and get adjusted.

You're a little anal sometimes huh?

I just crank the torsion bars up till the CV's cry for mercy, and whizz it down the tracking shop.

What are your ride height settings out of curiosity?

Your right Tony, I am very anal sometimes, just ask my girlfriend?


To set the truck up to the factory ride height do as follows;

Measure the height from the ground to the center of the spindle of the steering knuckle (wheel hub)

Measure the height from the ground to the center of the front side adjusting cam bolt (bolt that secures the bottom wishbone)

Subtract the two readings. The reading you need to obtain to reach the factory setting is 58.5mm (2.303in)

0.5mm accuracy, you must have some fancy laser thingy otherwise its too small to see.

However it is always nice to get things done properly so from that point of view I agree with why you did it.

Too much information.

That's why it took 4 hours work of adjusting and re adjusting the torsion bars to get it right. I'm sure it's not exactly right, but I filled her to the brim with diesel so that it gave a reading with it as heavy as it will get normally.

Considering I started out with a reading of 95mm, it was far to low. I had to apply over 12 full turns on the torsion bars just to get close.

This is what the info on the sheet from Toyota says;


Adjust the vehicle height to the standard vehicle height for wheel alignment inspection.

HINT: With non-loaded vehicles, there is a difference in the vehicle height according to the model.
Although the wheel alignment standard value changes according to the vehicle height, by setting the vehicle height to the standard height, the standard alignment value becomes the same for all models.

The vehicle has to be on the LEVEL as even a standard water run-off gradient on any hard-standing will alter the measurements. (Most internal vehicle bays are level but most outside -driveways etc. are not!)

you have some patience dont you!
i would of just went mad on that nut (now i know how) and then measured in the same place on each side.. gave it a nod and then put the kettle on

My ride height is better than perfect, I set it using three satellites in a triangle configuration at precisely two seconds to mid-day on June 21st.
Thankfully it was a clear day with good visibility, otherwise I could have easily got the passenger side one thou out.

I tried using a theodolite to set the camber angles but I had to be 20 metres from the truck to get a good reading and by the time I walked back to the truck the earth had rotated slightly so I couldn't get an acurate setting. No problem though, I just turn left every time I come to a junction now. Will this be a problem at MOT time?

only if you need to turn right into the test centre

I hope you set the drivers side higher to allow for your weight when you get into it??
