my front tyres on my isuzu 4x4 wear on the inside. ive taken it to numerous alignment centres.whats wrong?

Question

1998 isuzu KB twin cab 2.8 turbo diesel. replaced all front tyrod ends and ball joints.

Answer 1

what your rotation schedule it needs to be about 3000
are you shocks ok if the tires are cupped on the inside you may have a shock issue


ask a dealer whats up they are familiar with the truck

Answer 2

Place your hands together like a teepee with the fingers touching at the top and the palms spread apart....that's an exaggerated view of how your tires are angled because the camber adjustment is not set right. Yout tires should be straight up and down throughout their range of motion or they will wear more on the inner sides because that is where they contact the ground. Camber adjustment pulls the top of the tire inward more (negative) or outward (positive) from straight up and down depending on the steering geometry and should be adjusted properly to prevent excessive wear. A good computerized alignment shop can check this setting for you and show you the specs of what it should be and what it actually is. This site for a Jeep illustrates the various alignment checks:

Also, make sure to check that your tire pressure is correct and if you've had any front end frame damage from an accident, that might be a factor too.

Answer 3

you need to have a front end alignment done, just rotating the tires will only cause the others to wear also,
make sure your tire pressures are at the proper setting

during the front end alignment the tech. should be able to readjust the camber , the only other issue would be the front springs(or struts whichever is equipped on this vehicle) if they're getting weak they wont carry the weight of the engine properly causing the top of the tires to lean in from the extra pressure on the rest of the suspension
shocks wouldnt really cause this issue as they only act as cushions for the road bumps they dont really carry any weight like a strut or spring does

Answer 4

If they are wearing to the inside you a tow in problem. Jack up the front end just so the tires are off the ground take and wiggle the tire to see i your ball joints are bad. When drive the 4x4 does it drive straight or does it wander when you hold the steering straight . Do you have stock tire or oversize? If it is oversize you have change the the set up in the front end to fit the tires

Answer 5

I had a similiar problem with one of my Ford Rangers. Replaced the tie rods & ball joints, but still the wear on the tires appeared. Changed my oversized tires to a smaller size closer to the stock size tires and it eliminated the problem.

Answer 6

Torsion bars too tight. Camber set wrong.
