TIRE WEAR - FRONT - OUTSIDE EDGE
LIGHT TRUCK 1976-86 E100-150
Outboard shoulder wear, predominantly in lightly loaded city-delivery type use, is aggravated by excessive positive wheel camber in turning. The caster
adjustment kit described in TSB 85-19-15 can be used to increase caster of either wheel up to 3 degrees in 1/2 degree increments. The kit contains
complete instructions for modifying the front radius arms and mounting a metal adjusting cam to the bottom flange of each radius arm. Cams must be
arc-welded a minimum of one inch along two sides of the cam to the lower flange of the radius arm.
Increasing caster the full 3 degrees effectively reduces camber of the outboard wheel in a turn 1.5 degrees. Increasing caster more than 3 degrees is not
recommended since this may cause complaints of wheel shimmy and/or excessive steering efforts. Also, caster should not be increased on vehicles built
since April 1, 1984. These vehicles have the 3 degree caster increase
already built into the axles which have axle part numbers E4UA-6-BA and E4UA-7-BA embossed on the face of each axle.
Three other significant factors may also contribute to outboard shoulder wear. They are excessive toe-in (generally greater than 5/32 inch), excessive
cornering speeds, and low tire pressure. After any adjustments to front end alignment, toe should be adjusted to zero. On vehicles subject to extensive
city-delivery use, toe may be set up to 1/16 inch toe-out for optimum tire life.
