Jpri Posted April 16, 2023 Share Posted April 16, 2023 Going to be doing a bushing replacement on my truck. Never done this before. Is there anything I need to know about or need other than what’s in the photo? Also they are pretty wore, what are the chances the trunnion itself needs to be replaced?

Joey Mack Posted April 16, 2023 Share Posted April 16, 2023 take a look at the saddles from under the truck looking outward.. if the outer ring of the saddle is close to the inner ring on the trunnion bar,,, it is worn out.. How about you get a few pic's of the inside of the saddle, and trunnion bar in the A-Frame.. Many years ago, I used to put a magnetic dial indicator on the trunnion bar, and the pointer on the bottom of the saddle, 'Zero' the dial, then jack up on the trunnion bar (while watching the dial the whole time) till the wheels just came off the ground. then take that reading.. at,, .100'', we would call it ''worn''... when it was apart, the brass bushing would be paper thin on the bottom or close to it.. and certainly the bottom of the trunnion bar was worn,,, (D-Shaped)... jojo 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 16, 2023 Share Posted April 16, 2023 Get to know the torque value for the size of the u-bolts you have.... then figure out how to get that torque.. 1300+ lbft is not out of the realm of possibility.. jojo Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted April 17, 2023 Share Posted April 17, 2023 I see the Twinkies in the parts photo 🤣. had two torque multipliers .. long bar was 3/4 in 1in out . for this job the long handle made life a lot easier. Quote Link to comment Share on other sites More sharing options...
JoeH Posted April 17, 2023 Share Posted April 17, 2023 A thread chaser might be handy for the end of the trunnion bar. Ours was pretty worn away, but we managed to chase some threads clean enough for the clamp to thread back on.... Remember, the bar hangs from the spring. So put cribbing under the bar before cutting u bolts. Quote Link to comment Share on other sites More sharing options...

Jpri Posted May 3, 2023 Author Share Posted May 3, 2023 Anyone got a part number for the trunnion spindle? Pretty sure it’s the 3.5 single hole on the end but don’t have it apart. I’m seeing some of these are 4 hole at the end, 3 in, 4 in, nothing says specifically it’s for a 44k. Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted May 3, 2023 Share Posted May 3, 2023 Those stubby trunnion bars are new to me.. I wonder how they get installed.. the 4or5 of them I had replaced, I used axle surgeon.. parts and labor was $1500.00. but this was also over 5 years ago.. they put the whole bar in with welded on clamps..
