Any way to fine tune the rear tire toe and camber? Please help people! The best way to do this? Although the rear tire tread wear out evenly, the rear tire seems to be miss align? I know other XB are shipped like this because my bro in law has a XB too and he has the same issue.

Yes I would say its your toe also need to be adjusted the only other thing i can think of is the pin at the bottom of the rear bearing holders can be bent that will make the tires go a different direction.

But you have to understand my XB was shipped stock like this. I don't do any jump or bash the heck out of it.....

I think my toe is perfect cause the tread wears perfectly. The problem is the tire is pointing to the body? :D ......... :(

ey obeast44, can u provide pictures of where exactly are the blocks you meantioned? becus i cant seem to adjust mine either :) thanks
 
this toe in you have will make your xb turn better. but- it will scrub off speed- if you want to experment, remove the 2 long bolts that hold the rear diff -metal plate that holds the a-arm pins. look at the 2 plastic inserts that are attached to the metal plate-they are offset. reverse the 2 rear offset a-arm holders- this will give you less toe in- more speed- less turning ability. the front ends black plastic a-arm pin holders are centered- no offset. best to leave these alone. only make 1 change at a time to the car. in the xb owners manual these parts are called "bushes" the part # for the "center bushes" is-07173. the part # for the off set bushes is-07126. 6 dollars for 6 bushes. this is how you tune your cars handling- example- most sand duners fun zero toe in with the hpi buggies- this is a cheap-fun way to experment on your own to find the beat handling angles for -- pavement-hard dirtwith loose sand on top-soft dirt-ect-ect---
 
pardon my spelling- my fingers are cold- all 4 bushes on the front of your xb are center bushes. on the rear gearbox housing - the rear 2 bushes are off set. the front 2 bushes are center bushes. this provides about 4 degrees toe in- this is hard for me to explain - but do you see what i say? - its really a e-z way to set up your car- put the car on a stand and eyeball the wheels angles you get with reversing the 2 rear off set bushes- you will get the hang of tuning in record time-

They are the little black plastic hinge pin retainers. Just flip them around or get the centered ones to select the desired toe.
 
Here's the center ones

and here's the ones that should have come stock, which you can flip 180 degrees depending on what you want.

I run 3 degree rear in on most my RC's. T4 stadium truck and slash 4x4 included. I run my short course truck with front toe-out because the longest straight section is 8 feet. I'm pretty much constantly weaving in and out of hairpins, chicanes, ect.

The biggest effect toe has on the handling of the car is on stability. When a car hits a bump or enters a corner, forces on the tires act to steer the car off to one side, making the car unstable and difficult to control. Toe-in counteracts this, improving stability. Toe-in also causes understeer during initial corner entry. Interestingly, toe on the rear wheels has the same effect on handling as toe on the front. Toe on the rear wheels is useful for tuning the handling of the car as it is exiting corners.

Front Toe "IN"

Slower steering response

More straight-line stability

Too much will casuse greater wear at the outboard edges of the tires

Front Zero Toe

Medium steering response

Minimum power loss

Minimum tire wear

Front Toe "OUT"

Quicker steering response

Less straight-line stability

Too much will cause greater wear at the inboard edges of the tires

Less Rear Toe "IN"

Less straight-line stability

Less traction out of the corner

More steering

Higher top speed

More Rear Toe "IN"

More straight-line stability

More traction out of the corner

Less steering

Less top speed
 
my bajas are the same way out of the box. the rear wheels are toed in a couple degrees. it helps with handling and straight line stability as imminint and alfred say in the above posts. this factory setup will give you the best all around performance. you can tune it further for specific conditions or tracks, but this may give you undesired handling characteristics. basicaly i wouldnt try to correct this just because it looks funny, its like that for a reason. but if you are unhappy with the way it handles go ahead and play with different alignment angles untill it handles the best for your own uses

Thank you for the great response. Very helpful!
 
You have to change the bushings (part 07179) they are the offset bushings.Either change them to the center bushings, or reverse the offset.
