Changing trailing arm crossmember
 

Can you change to a PB trailing arm crossmember without pulling the cab? Mine will be here tomorrow and was hopeing I could just drive some rivets out and bolt it in. Thanks for the help!

You can, did mine that way.

Biggest trouble I had was drilling the new holes square to the frame on the top. A heavy duty right angle drill motor would help.

Hey guys sorry to bring up this super old thread, but I am curious how you go about drilling out the top rivets when the cab is still on? I want to change my TA crossmember as well but definitely do not want to remove the cab if it isn't 100% required! thx

Use an air chisel to take the heads of and then drive them out. .

But can you do that with the cab on? Doesn't seem like a whole lot of room between the top of the frame and the bottom of the cab to do that...

You can get to them from the bottom side. It is a real pain to do it with the cab on. If you are not saving the old cross member take and cut it off with a sawsall close to the frame to get it out the way and it eases getting to the rivets with the air chisel.
