eating front tires

[bsevans]

+7/16' toe out???? It's a wonder you can steer the thing straight down the road. Depending on your tire size it should be set around negative 1/8 - 3/16" or 'toe in'.

Figure out why and fix it! If the TR is bottomed out on the TRE's, thread the TR deeper or trim some off one/both TRE's so they can thread in deeper and don't bottom out in the internal threads in the TR.

The toe-in for HR78-15B tires is -.04 to +.04. For modern tires it is + .12 to .20. This is straight out of the FSM. I think negative toe-in on a 33x10.50-15 would lead to more drifting than slight toe-out and would make turns a little too edgy for my taste.
If the shop you are having the toe-in adjusted at don't understand how to correct it, then take it to a more reliable shop.

If it doesn't pull, you can forget about the caster & as the man said, camber is adjusted with shims...

I think you have your terms reversed. Please enlighten me with a web link or reference to a specific page in your FSM where this adustment is explained. In my FSM, these are addressed on page 7-72.

There are several places one can measure caster an uncut, straight FJ40 axle, listed here noting ease of measurement:

#1. Is the easiest to do with the axle assembled. This surface is 45 degrees from #2 and #3. This method is the easiest and most reasonably accurate method in my experieince.

#2. Third member mounting surface. On an an 'uncut' axle this surface is the exact same as the caster measurement #3.

#3. Here's what you are really after. A little harder to get to but will be the most accurate.

#4 is the second easiest but requires one to remove the driveshaft. This is the same as measurement #2, just taken another place as the two surfaces are parallel.

It can also be measured (abeit possibly not as accurate) without disassembling anything by measuring on top of the assembled steering knuckle. It takes like 30 seconds and will get you pretty close.

When you say: "It can also be measured (abeit possibly not as accurate) without disassembling anything by measuring on top of the assembled steering knuckle. It takes like 30 seconds and will get you pretty close", the car must be in jacks with the tires? or it isn't necessary and measure directly. Also how many degrees must be read in the angle finder instrument?

Thanks
