Fits 1979-1985 Toyota front solid axle knuckle.

Normally the nuts that hold the wheel bearings can be reused over and over again. If your wheel bearing retainer nuts need replacing this kit is for you. Kit contains 2 nuts, star washer and flat index washer.

The brake backing plates can be a bother on front Toyota solid axles. They often get bent from trail damage and small rocks can get trapped between the backing plate and the rotor causing noise and damage. For many years we have taken the stock brake backing plate and cut out the center section. Then we would reassemble the axle with just the center part for spacing.

We have come up with a cleaner way to accomplish the same thing. Our Backing Plate Eliminator kit contains two spacer rings that take the place of the factory backing plate. The rings are the same thickness as stock for proper component spacing. Installation is easy, simply remove the stock backing plate and replace with our rings when your servicing the knuckle.

We have had a lot of people tell us they don't like the stock inner felt plates because they are so thin and are easily damaged in the rocks. Well check out this trick solution... super heavy duty rings made from 1/8" (.125) material. Stock covers are just .040 thick. That's over three times thicker than stock! These bolt on exactly like stock units. Sold as a set of 4 plates for doing both front knuckles. Fits 1979-1985 Toyota solid front axle.

A pull scale is helpful in setting up the shims on a knuckle. By increasing the shims above and below the knuckle the knuckle becomes tighter. When installing new knuckle bearings we recommend checking the shims with a pull scale. Attach the pull scale on the steering arm with the tie rod / drag link removed and the felt on the back side of the knuckle not yet installed. The knuckle should not move until about 15 lbs of force is applied to the steering arm.

When assembling your spindles gaskets does it feel like your all thumbs? This kit contains 16 studs and flanged nuts. With studs installed it's easier to install the spindle gaskets. Gaskets are placed on the studs one at a time, then nuts are install on the assembly.

Wheel Bearing kit includes inner and outer bearings, hub gaskets, inner wheel bearing seal and star lock washer. One kit services left or right side.

Stock replacement rear axle shafts. Breaking strength of 7100 - 7400 ft-lbs of torque. Applications to fit 1979-1995 Toyota Surfs and HiLuxes.

4340 chromoly inner hub gears. With stronger axles than ever before, the next weak link has become the inner hub gears. When the hub gear breaks it strips the splines on the Burfield. Then the Burfield needs to be replaced. This costs a lot more than upgrading your hub gears. We have available a bullet proof inner hub gear to solve this problem.

We also have them for IFS hubs for the same price. This will convert them over to straight axle hubs.

This is an OEM style, 27-spline birfield made entirely out of 4340 chromoly material.  The material upgrade makes this birfield much stronger than stock.

Note: All Trail-Gear products carry a one year warranty against defects. This warranty covers defects in material and workmanship. An example of a covered defect would be a missed machining step that prevents installation or a significant internal material void. This warranty does not cover normal failure or breakage that is typical when using stock joints in extreme conditions. 4340 Chromoly Birfield joints will not hold up to extreme usage with oversized tires.

Heavy duty drive flanges for Toyota solid front axles. These flanges are much stronger then factory drive flanges or lock out hubs. Flanges feature a larger center section with more support for the splines. Made from hardened tool steel (4340 Chromoly), these hold up much better to the kinds of toque possible with today's heavy duty aftermarket axles. Kit includes 2 flanges, 2 dust covers, 2 cover seals, drill bit and 12 heavy duty studs. Additional studs share the load, preventing hub stud and bolt failures common to stock drive flanges and hubs. Flange covers feature a Trail-Gear exclusive O-ring for a water proof seal.

If your running stock hubs on your truck, drive flanges make a great trail spare for your tool box. If your stock hub gears fail on the trail, drive flanges can be quickly installed to restore 4wd. Fits 1979-1985 Toyota Pickup/4Runner solid front axles. Recommended for off-road use only, not recommended for use on the street. We recommend that flanges be painted before installation.

As above
