    All-Pro Upper Control Arms

    I was wondering if anyone had installed the All-Pro Off Road Uniball Upper Control Arms. I asked All-Pro if they would fit a 3rd gen 4Runner and they said they should. But I was hoping I could get some feedback from people who actually installed them.



    How come they're so cheap compared to TC or Inland Trucks Uniball UCA's? They're almost half price. All-Pro also mention that theirs are slightly longer, but that you can still align the truck to stock specs. I remember the original ATS UCA's were too long to allow the 4Runners to be aligned properly and don't want to have that problem should I decide to go with the All-Pro's.

    All comments welcome, within reason of course.

    What could have caused it ?

    The upper control arms keep the rear axle from moving side to side. They also eliminate any pinion angle deflection that can botch traction. The lower control restrains the rear axle from moving front and back, just as the leaf springs on older model vehicles and most trucks, the lower control arms transmit the force from the wheels to the chassis. Of course, the four-link system is much lighter, and more effective in preventing axle wrap than the traditional leaf spring set up.

    For those who don’t know, axle wrap is torque and traction combining to twist the axle, pushing the nose of the differential up going forward and down going backward) by twisting the axle into an "S" shape. The energy is stored in the spring until the tire slips, and at that point the spring snaps back violently. Sometimes this results in a hopping sensation, hence the other common term, "axle hop." It can be very hard on driveshafts and u-joints.

These upper control arms feature Clevite OEM style rubber bushings and pressed in ball-joints for easy installation. They allow for full downtravel and increased clearance to the upper strut mount.
