Axle pivot bushing

Axle pivot bushing removal
Drill out rubber by drillling lots of hole in the rubber on factory bushing and push out
Take a cold chisel and bend over side of bushing into center of bushing


Then press out bushing, I pounded them out
They came out EASY
I put bushing back in for photo
I know it is crooked


Bushing out


This is how it looks after it is out

Axle pivot bushing installation

Make sure you get Poly bushings
Make sure they are going in straight
Make sure the new one goes in the same way that the old ones were in the arm
Ball joint press is the EASY way

New Radius arms

I put in new radius arms and poly bushings. Arms are factory ford
$99 each from Jeff's Bronco Graveyard
I bought NEW top bolts that hold radius arms to TTB arm
The bolts are available from Ford ($12.50 each)
I cut the old bolts shorter so I could get a short 6 sided impact socket on
Have new bolts in hand BEFORE cutting old ones
3/4 inch breaker bar with 6 foot pipe and they finally broke loose

I took the Dana 44 carrier out to lighten the arm
drivers side
I know the bolts are loose


Passenger side

DO NOT CROSS THREAD BOLTS
put oil the threads
DO NOT use anti-sieze on threads as they will come loose

spring install

Tightened the bolts that hold radius arms to TTB arm
Bought a 3/4" torque wrench at harbor freight that goes to 300 ft/lbs ($80)
cranked the bottom bolt a little more to get the 320-340 torque spec for lower bolts
Put springs in
Tighten radius arm to frame bracket nuts to torque spec
drivers side


Passenger side

That's all for today

good luck, those are a bastard to R&R while out of the truck let alone leaving it in the truck, and there isnt really a way to leave it in the truck because its the main thing holding up the TTB

i could be way wrong on this but i have personaly tried doin it in the truck and it was almost impossible

I did mine... you have to really, really think it through. It's not only hard but dangerous, if that TTB gets away from you it'll break stuff in its way.

I used a couple of floor jacks, several jack stands, and backed up everything with stacks of bricks and 2x4s. I used an air hammer to punch out the bushings, and had to modify the press a little to get clearance to put things back in.

It was several years ago, wish I had taken pics... I remember pulling a bolt and having one TTB arm slam into a stack of 2x4s. If they hadn't been there, it would have been a real mess. The movement was not what I expected. Proceed with caution if you go this route.

Also, all that work didn't cure my Death Wobble. It was the TTB bracket. One hole got wallowed out. Re-welded and drilled it, then got a new one ordered. Been good for 3 yrs now.

Whenever my truck would get death wobble I knew it was time to tighten the bolts holding the ttb drop brackets on.

They're welded now.

Why? There is no need to remove the rubber. On the one I just did all that was needed was to bend in the slight chamfer on the back side of the bushing and punch it out.

Yeah, so why go to the trouble to drill out the rubber? Seems like a wasted effort for no gain.
