Here is the first installment of how to build an adjustatable caster system for your FJ80 radius arm front axle. Toyota has graciously supplied us with most of the required parts to perform this mod from the cam bolts to the metal brackets they ride in.
The weld on brackets could be fabbed up and the cam bolts purchased from Toyota. However, purchasing the the lower front frame chunk from an 86 - 95 Toyota IFS mini truck or 4-Runner 4x4 will give you all the required parts and run about $10 - $20 from a salvage yard.
Picture of the mini frame section.
Picture of the lower bracket sections which were cut from the lower frame section and new cam bolts (the old bolts were a bit crusty).
Part #'s for cam bolts (2 of each)
Cam assy, camber 48190 35020
Cam, camber adjuster 48198 35010
Nut 90179 16005
More to come later today or tomorrow.
More... well, a little bit.... The weather was just soooo nice today, I decided to take off on a mountain bike ride with my father. I did manage to slot the stock brackets for increased caster. OOooooooo, ahhhhhhhh..... try to pick your axle up like that with a stock track bar connected, note angle of joint.
Despite the offer for another bike ride, I chose to stay in the garage this afternoon. In the picture below, you can see the mini brackets installed with all gusseting and such. They are rather easy to place on the existing bracket with a few tacks. The top of the slot on the mini bracket aligns with the bottom of the stock hole, if it was still there... lmk if that is not clear. Large gussets are run rearward and forward. I decided to sort of 'box' the front to help the bracket resist the twist that articulation induces, this should help prevent tearing or cracking of the welds. More later.
Here is the completed mod... I'm sure a few things were left out, I will ad them as I remember. Another bonus to the mod is the ability to change the pinion angle, although it obviously will change caster at the same time, a happy balance could be reached. Ask any questions if you have them.
