Polyurethane Axle Pivot Bushings
Energy Suspension's Axle Pivot Bushings will restore alignment lost to worn bushings. The heavy I Beams in Ford trucks can quickly wear out rubber bushings. These new polyurethane bushings are tough enough for off road use yet compliant enough for everyday driving.
  • One Set Will Cover the Left and Right Side
  • Must Reuse Existing Outer Metal Shells

If you have a Ford F-Series Truck or E-Series Van this polyurethane axle pivot bushing replacement is a much more durable replacement than an OE rubber bushing and will do a better job of holding the alignment of your Twin I-Beam axle.

Signs of a Bad Axle Pivot Bushing

  • "Clunking" noise from under the hood
  • Feeling a bump under your feet after turning
  • Wandering steering after a bump
  • Loose feeling in your steering wheel

Is your Ford Wandering?

Normal wear and flexing can cause the rubber axle pivot bushing In your Ford truck or van to sag or wallow out, loosening the once secure connections between your I-beam axle and the frame. This can cause a steering wobble, or even make the steering wander to the left or right. It can also cause the loud clunking under your feet that you might have heard after hitting a bump.

Energy Suspension has made a Polyurethane axle pivot bushing that will toughen up this connection. These Polyurethane bushings maintain a secure connection between the axle and the frame and will tighten up the slop in your steering and assure that your alignment holds true through every suspension movement.

The Durable Choice

You can purchase an OE rubber replacement bushing that will do about as good a job as the original, but eventually, it will have the same problems. Polyurethane is much stronger and more durable than rubber and can hold its shape in spite of the weather and everyday road wear your Ford goes through. These bushings will not need to be replaced for the life of your vehicle, and we here at DST provide an exclusive lifetime warranty on these polyurethane bushings.

So if you want to get rid of that clunking under the cab, or looking to get a tighter feel in your steering, Energy Suspension polyurethane axle pivot bushings will serve you well.

starstarstarstarstar" A worth while update but youll have to earn it "

This is a difficult job; mainly because removing the old bushings was hard. They were bonded to the metal and didnt want to release the grip they had and wound up coming out in pieces. Because of the weight of the I Beams I did all this with the arms in the truck and laying on my back. As for the new bushings, they go back in relatively easy and solved a clunking problem I was having. Once it was done I was glad I made this upgrade but it was not easy.
