Outer Limits 4x4 Board

I put 7" springs under my 80 with castor plates (which i was told r 7 degree). Anyway the car wanders like a dog on heat!!
Took it in to get a wheel alignmet and they informed me that i had 2 deg positive castor and that it sould be in the neg......
Wondering if i dropped the front trailing arms down from the chassis how far would i have to drop them to get the diff to rotate back 3 degrees

mate nice rig.

ahhh save ya money and learn to live with driving a pig!

keep you alert on long drives.

Do you mean castor?
As far as I am aware camber is not easily (at all) adjustable?

bend your housing....does a good job of altering your camber

Generally speaking I beleive the cruisers do sit with slight positive camber. Tis a worry if it is negative, as you have either bent your housing or your king pins (???) are extremely worn.

sorry i do mean castor

Have heard of these castor plates being a little rough in the 'guestimation' of castor. ie 5 deg only being 1 etc

If you have too much castor it may very well be giving you the wobble.

Did the wheel alignment shop offer any advice? Go to a 4wd place to get alignment as normal alignment shops are not real good for 4wd.

Pretty sure positive castor is what gives you return to centre feel in the the steering. If you have too much though it will cause probs.

Hi
You wont be able to get it back to where u need it with just the 5 degree plates. Caster should be neg 1 but +1 is acceptable, aslong as it is not 0.
U can invert the lower control rods to get it all working, or run front relay rod as in 75 series.

What about drop boxes like they use on patrols..

Invert the lower control rods?? more info......
r the arms on a 75 any different??

Hi Lance, what happens is you flip the lower arms to be ontop of the diff, and flip the panhard to clear the new arm position.
Slowhilux had a piccy of this mod, but i couldnt find it looking through his posts.

You can get castor correction bearings. that is the ibearings inside the front hubs which the hub pivots on when you turn. You can get them where the bearings are off center and it should fix up ur problem

Hi These are camber adjustment bearings you are talking about. U use them if u have a bent diff from jumping or hitting something
Andrew

Thanks 4 that dow50r

Thats ok Ray
If u put skinny tyres on the front, it will be noticeably better to drive. Bottom line here is your plates are not enough correction,and you cant go further till you address the steering rod hitting the lower control arms behind the front diff. There are special control arms u can buy that are shitloads of cash, or you can get rid of that rear steering arm by running front steering as in 75 series (and swapping swivel hubs left to right) or cheapest would be to flip the control arms to ontop of the diff, getting the caster corrected as u go.(then the rear steering arm is below the arms and doesnt hit) I think Sam from Overkill (Sydney) does this. One other benefit of this is your diff goes back forward and tyres dont get as close to the mudflaps
Andrew

this is what i mean about how close the steering arms are to the control arms..


The steering arm actually touches the control arms when u turn

There is a guy I know here in sydney that has played around heaps with the toyota control arms.. I have seen the work he did on one cruiser and it looks awsum! He set up the control arms on to the top of the diff... PM me if you want his details.. I do believe he is opening up his own workshop soon... Oh, he also does work on my 4WD... And will be doing more as soon as my back pocket opens up more...

Drop boxes will lower the control arm by about 4" at the chassis end. Therefore providing clearance for the steering. Someone tell me if im wrong with this..

The arm flip is a good idea, the front end works heaps better on and off the road.
