Any cab mount bushing swap tips?

Post by 69timemachine »

My body lines on the bump are a little out of whack, and since I hope to one day upgrade to a TKO-600 transmission and will need to maximize floorboard clearance, I'm going to install new cab mount bushings. I ordered the 12-piece poly bushing kit, and since my truck has been garaged for most of its existence, I think my bolts and washers should be reusable. I found several topics on the subject, but still have a question. Do I need to disconnect anything like the steering ragjoint or clutch rod when swapping the cab bushings? I know not to jack the cab up but just enough to slide the old ones out and the new ones in, but any special procedures I should know about? Thanks! :thup:

i'd unbolt the ragjoint and pop the clutch linkage off as well just to be sure,i ripped a ragjoint by jacking the cab up to do a quick and nasty cabmount replace once ... :roll: .... at the least i'd unbolt the clamp and plate on the firewall holding the steering column (and either loosen or remove the bolts holding the column to the dash)

also: the old bushings can be a real P.I.T.A. to remove sometimes- especially the rear ones for whatever reason,you'd think that since they're pretty much protected from the elements they'd co-operate and leave peacefully,but they never have for me - goodluck!

Yes, that's what I was thinking, that all the solid-mount components should be disconnected. The brake lines and radiator hoses should flex enough. I suppose I better watch the fan shroud too! :thup:

Do you still have the front clip on? Lifting the cab more than a half inch or so might put stress on the fenders being bolted to the cab and the radiator support? Probably enough flex in the rad support bushings not to make a difference. Just thinking out loud. Only other thing I can think of would be the speedometer cable and the fuel line if you have an in cab tank. E brake cable's probably got enough slack in it.

The truck is still 100% assembled and drivable. My basic plan is to:
1. Disconnect anything that would bind
2. Remove the LH core support bolt and LH F/R cab mount bolts
3. Use a couple floor jacks to raise the driver's side of the cab/core support/fenders assembly slightly
4. Swap in the new bushings for the old
5. Set the assembly down and replace the LH side bolts
6. Repeat steps 2, 3, 4, & 5 on the RH side
7. Tighten all the bolts down and reconnect everything

Think there's anything I'm overlooking in this plan?

Nope. Sounds like a winner. Good luck and keep us posted.
