Popular Post Joey Mack Posted October 29, 2022 Popular Post Share Posted October 29, 2022 When you use the impact gun to remove/install the yoke nut, do the best you can to hold the yoke with a homemade tool or your hand to keep the hammering of the gun from causing a clashing of the gears in the rear end.. do not rely on the ring and pinion to be the holder for the impact gun... jojo 1 2 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted October 29, 2022 Share Posted October 29, 2022 Very good advice! I always worried about that….but never applied a tool. Quote Link to comment Share on other sites More sharing options...
Adkat Posted October 29, 2022 Share Posted October 29, 2022 I use a Makita 18v 3/4" gun, usually works well, if not, gas axe on the nut to free it up does the job. You can also cut some shims out of an aluminium can to tighten the caps up in the straps if the uni is still in good nick. 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted October 29, 2022 Share Posted October 29, 2022 good idea about the shims.. here in the states we get trained to "Replace" but a "Mechanic" can re-use and Fix it !! I have a hard time, at times, explaining that you can, "Fix It!" jojo 1 Quote Link to comment Share on other sites More sharing options...
Adkat Posted October 29, 2022 Share Posted October 29, 2022 Yeah 9 times out of 10 it's a replace job, but if the seal ain't leaking, the yoke ain't loose and the unis good , can't see any point throwing money away unnecessarily. 1 Quote Link to comment Share on other sites More sharing options...
The Nitro Posted October 29, 2022 Author Share Posted October 29, 2022 I have a yearly inspection coming up so just bought the parts already. Was deciding wether to get the 40v makita 3/4 or a bigger 1 inch air gun. The cordless would be preffered as i could use it for other stuff out in the field if its up to the task. I thought about the soda can trick but my luck if would half fall out on the way in fir inspection and they would see it and kick my ass lol Quote Link to comment Share on other sites More sharing options...

The Nitro Posted October 31, 2022 Author Share Posted October 31, 2022 I found a 40v makita 3/4 impact a few towns away and got it sent over. Walked around all the tool shops in our town wirh the new nut in my hand and no one had a 56mm socket to fit the nut lol. thought I was in luck in one shop when I saw a shelf with the big sockets on the wall. Walks over and they had a 55 and a 57. 56 was gone haha. Will have to order one. Trucks grounded anyway as I wait patiently for new electric tarp cover to be made by local upholsterer. Been waiting 3 weeks for the actual material to turn up. Starting to thing theres a shortage maybe. Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted November 6, 2022 Share Posted November 6, 2022 I wish I had one of those, back when I was doing road service work.. Heck, I never even thought to look into buying one... $88.00 What a deal!! jojo Quote Link to comment Share on other sites More sharing options...
The Nitro Posted November 12, 2022 Author Share Posted November 12, 2022 I had no luck with the rattle gun on the yolk nut. Ended up using dremel and whittling away at nut and the flange of nut as well since it was glued at thread and back of nut flange. Quote Link to comment Share on other sites More sharing options...
