Torsion Bar Adjustment

[avstanley]

I just finished up installing new upper and lower control arm bushing as well as lower ball joints on my 1995 4runner. I need to set my torsion bars back to stock now and can't seem to find the specs for this. At one point, years ago, I had found a spec that took a measurement from the stock 15" rim lip to the fender whith the vehicle sittig on the ground. The FSM list a spec in wich you measure multiple things and figure out the difference. This is some what combersome though and I was wondering if any one had heard of simply measuring from the rim to fender. If so do you know what this measurement shoiuld be?

Model and year?

Torsion bar adjustment will vary depending on wheels, tires and the ground your on.

[avstanley]

It is a stock 1995 4runer 4WD V6. By measuring from the lip of the rim to the fender lip it takes the tire size out of the equation.

[CJM]

Your rim will ride different with different tires due to sidewall variances (height and stiffness) and tire pressure even in the same tire size dude.

Thats why they have that calculated figure.

I wish I had the measurement, I would say its probably 12-14 inches or so tho.

Actually it usually measured from the center of the hub to the fender, so it doesn't matter what size rims or tires you have. I don't remember what the number was though. Sorry :(

But if you are measuring from the top of the rim to the fender it doesn't matter if its a 35x15 or a 28x15, fender to rim distance doesn't change with tire size.

[Crinale]

make sure you are on completely flat and level ground, and (assuming you have 15" rims) the distance between the rim and fender (for stock height...) should be around 13.5-14"... if you do any off-roading at all though, you can play with adjustments larger than that however...

when you do adjust them, make sure you measure it, then drive around the block, making sure to hit a few bumps to cycle the suspension a little, then remeasure, as the bars will settle a little bit, and might need to be readjusted.. do this until you are happy with the result

No, your tires could be completely flat and it won't affect the distance from the fender to the rim (assuming all 4 tires are flat).

avstanley, 13.5-14" like Crinale said.

I stand corrected.

Another nod for the 14" distance. Find a safe spot to drive around at also and take some low speed runs, like an empty parking lot and do turns and stops to be sure you don't set them too soft and end up with front end dive that's too excessive.

Next time I do a set I should remember to count the turns from start to when the bolt is flush with the top nut, problem is, most of the time the bolt ends up breaking off within 4-5 full turns due to age and being frozen in place so long.

[avstanley]

Thanks for all the input. Currently I am at 15", I will probally go ahead and back them down to 14" and try it there.

I knew I'd read this spec info somewhere. Realize the measurements are a subjective measure, from step 1 of page SA-4, where the difference from A-B remains a constant regardless of tire size changes. Now, if you added in some balljoint spacers it again would change accordingly based upon the geometry. (IE: Hypotenuse might slightly increase because the run remained constant while you changed the rise.) If you were to tighten up your torsion bars to get a leveling effect, this distance will also change. IIRC 15"-15 1/2" is the recommended maximum before you screw with the camber too much and start to affect the handling. This is why bracket lifts use multiple parts, to correct it all at once.

Got it?

Here's the tech: http://www.ncttora.com/fsm/1990-1995_4Rnr/Toyota.4Runner.1990.1995/FSM/95toypdf/95rmsour/1995/954runne/sa/wheelali.pdf

BTW..ROFL..Tech Geek? It's worse b/c I can read the second line leet..

"These are just some of the gang signs implemented by 1337 Hackers."

haha norcal... those gang signs are great... and that line of 1337 is super easy, its not even full 1337...

but talkin about 0|_|>3 3|\|6|_15|-| is just wrong :-P ... im younger than you are.. haha

and i can read this stuff almost as easily as plain writing.. just takes forever to type... haha

What I mean was when this whole 31337 talking thing was really taking off it didnt interest me much cause I was already somewhat older. I never really picked much up either
