j hancock Posted June 12, 2019 Share Posted June 12, 2019 Initial cost is about $3,000.00 plus shipping for an aftermarket piece. How much can you do? Don't know what a shop might charge. https://www.stengelbros.net/product.asp?gclid=EAIaIQobChMIn9yytPnj4gIVB_5kCh1C7AsGEAkYASABEgKcxfD_BwE&itemid=7211 Quote JimIt doesn't cost anything to pay attention.

It's a whole bunch of heavy work!! terry Quote Link to comment Share on other sites More sharing options...

Rob Posted June 13, 2019 Share Posted June 13, 2019 Last summer I installed one of the multi piece Stengle Bros. pieces on a garbage, (rolloff) truck. If you can stand the price, it is the one to use citing what has been stated already. Not a hard job, but heavy. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Why? What's broken? Trunnion bar? Trunnion cross member between the frames? Trunnion tower? Not enough info! Sounds like we might be telling you to do more than you replay need to!

JoeH Posted June 14, 2019 Share Posted June 14, 2019 The trunnion bar on our 1980 dm686sx broke years ago, got it off the ground and dropped old one out, new one in and we were good to go! You must have really stressed the truck if you broke the trunnion tower or cross member... Quote Link to comment Share on other sites More sharing options...

I would guess maybe the tower rotted out, they will rust out where the tower sides come down to the trunnion. terry Quote Link to comment Share on other sites More sharing options...
JoeH Posted June 14, 2019 Share Posted June 14, 2019 My trucks never see road salt, but it's hard to imagine the truck frame outlasting those towers due to rust. Quote Link to comment Share on other sites More sharing options...

Mack Technician Posted June 14, 2019 Share Posted June 14, 2019 (edited) We’ve accomplished some pretty miserable trunnion removals. Dealership only installed OEM. If your willing to remove some members(or a pusher), pop one side lose on every member up to transmission, and manipulate the trunnion toward chassis center, and you have enough hydraulics, you’ll pop that sucker out with pintle plate and hinge in place. www.diaglebrothers.com vends a member our dealership designed in conjunction with their fabricators. It’s a member that anchors the inner tower to the outside and inside of the frame rail with two additional flanges. Once installed you can’t lose a trunnion unless you find a way to shear a tube. Made for Quads and Michigan trains. Edited June 15, 2019 by Mack Technician Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted June 15, 2019 Share Posted June 15, 2019 On one of mine I paid 2100. to my door and 2000 to have Tulsa auto spring install in a dump truck.I think that was ok.This was the one from stengle bros which is a drop in.The mack dealer here sells some ,like it also.

Moparmike Posted June 17, 2019 Author Share Posted June 17, 2019 I've had it done its holding ok but I'm not a big fan of it cause it's hard to get in there and weld it right But I've had it welded to make it pay for the work itself Quote Link to comment Share on other sites More sharing options...

JoeH Posted June 17, 2019 Share Posted June 17, 2019 That I would replace. Hard to keep cracks from spreading. Some of the metal used in there is 1/2 inch thick. Your welds will need to be at least as thick to bridge the two pieces being joined back together. But the crack is in there and it's just a matter of time til it spreads.
