So if you order Bilstein 5100 Tundra then you will need to push out the old bushing and push in a new (3/4") bushing into the shock. This applies to the rear shocks, the fronts don't need any bushings to be pressed in or out.
This is one way it can be done.
Tools Needed
3/4" deep well socket
Impact gun (or strong arms and a 1/2" ratchet)
32 mm socket (rent from AutoZone for FREE)
Pitman puller (rent from AutoZone for FREE)
Crescent wrench
Supplies Neeed
Shocks
3/4" bushings
1/2" x 5" carriage bolts and corresponding nuts with a few washers
Pushing Bushings Out
Get out Pitman puller.
Add a few washers to the end of the Pitman puller. This is done for two reasons. One, the shaft on the puller will fit into the bushing, jamming into the bushing. Two, the shaft isn't long enough, so you need the washers to push out the bushing.
Put on shock.
Crank down (your choice: man or machinery). Should look like this.
Keep cranking down until you have this out.
This is the end result.
Pressing Bushings In
This is where you will need the 1/2" carriage bolt.
Make a setup like this with the 3/4" rubber bushing.
Using crescent wrench tighten down.
This should be the end result. If you go too far then switch over to the other side.
Done!
Obviously this would be done another way, pressing the bushings out only using the 32mm nut. However, I have not tried this method. I am very sure it would work though.
And a h/t must go to rickashay and 004RunnerLtd for their help and bouncing ideas off them with 004 giving me the Pitman idea.
