When Changing Cab Bushings... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

be sure to put your tranny in LOW or just disconnect it period. I just got back from the transmission repair shop. Cost me $160 to have the internal parts replaced. I had jacked the front of the cab to replace the bushings under the rediator and I heard a BANG! Turned out it was the tranny shift lever linkage inside the pan that blew up. Lots of pieces in the pan. The guy said it was lucky it would still go into all gears. Could have just as easily failed in forward or reverse. I had the select lever in PARK, thus, putting strain on the shift linkage all the way down to the lever on the side of the tranny. That's behind me now, but beware if you do this yourself. LBJ

Hmm, in this write up, they replace the bushings on one side at a time, left and right. I wonder if this would of prevented the stress of the tranny?

These are the two right under the radiator. Not really enough to measure left/right. Not raised enough to cause a problem, or so I thought. I did the others left right, one at a time.

OldrustyC10,

You might want to try the synthetic urethane bushings from Summit or another performance shop. I've got some pics of the new and old. I'll see if I cant find them. The new bushings make a LOT of difference in the ride quality. I noticed it RIGHT off when I took it out. Here's the old ones with the new box. They were in pretty bad shape.

I used the write up that cc posted, and followed to the letter and had no probs at all, though mine is a manual tran. I did the two up front also and used the poly, and have no complaints and think the cab sits straighter. Mine also had big flat spacer/washers with the old, wich I made sure I put back on correctly. lots of luck bob
