h67st Posted April 11, 2018 Share Posted April 11, 2018 YOUR U-JOINT IS ALL CAPS? Sorry, just couldn't resist. Do the caps have 2 bolts in them? If so, pull the bolts out and try smacking on the yoke where it's welded to the driveshaft tube (be careful, don't hit any important parts). If it's stuck, you can either use a u-joint puller or beat it out with a sledge hammer. You have to be careful with a sledge that you don't dent the driveshaft or bend the yoke.

Remove the bolts, push the joint to the extreme of one direction, tap with a chisel and remove that cap, flip the tiger tool and pull the joint fully the other direction. You can now remove the "cross" of the joint easily and a punch readily removes the cap from the other end of the yoke. That is on a driveline I wish to put back together without changing the joint. One that is expended I just blow the cross out of it with a torch, warm the ears of the yoke just a bit, and push the caps out with a drift pin and hammer.

alex g Posted April 11, 2018 Share Posted April 11, 2018 I put jack under yolk and Jack it up enough to have pressure on it and give it a hit with a sledgehammer. Sometimes use heat with that too if there stubborn. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53072-u-joint-with-4-capschange-out/#findComment-396377 Share on other sites More sharing options...
Vladislav Posted April 11, 2018 Share Posted April 11, 2018 These were made in 1945 and went out relatively easy. And with no heat. Good thing someone greased the shafts in the past. Probably the last time in 1983 though. Pretty sure nobody ever removed the caps after they got in place at the factory. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/53072-u-joint-with-4-capschange-out/#findComment-396397 Share on other sites More sharing options...

Used to do it that way too but the Tiger tools make the job much simpler and never damage anything. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

hatcity Posted April 11, 2018 Author Share Posted April 11, 2018 thanks all. had a feeling that would have to knock out caps before anything else. Comes with the territory. Will put a dab of nevr-seize around yoke before install Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/53072-u-joint-with-4-capschange-out/#findComment-396399 Share on other sites More sharing options...

Maddog13407 Posted April 12, 2018 Share Posted April 12, 2018 tigertool is one of the best inventions known to man right along with a set of slack adjuster pullers but tiger tools are pricey. usually $300-350 depending where you get one Quote Link to comment https://www.bigmacktrucks.com/topic/53072-u-joint-with-4-capschange-out/#findComment-396422 Share on other sites More sharing options...
Rob Posted April 12, 2018 Share Posted April 12, 2018 They are now selling direct again. I purchased a lot in December of 2007 and they quite selling direct on 1,1,2008. The resalers jacked the pricing up through the roof and their sales plummeted. What is old is new again. Ask for a discount if you are a professional trucker or repair facility.

Rob Posted April 12, 2018 Share Posted April 12, 2018 dont' get an OTC puller although they are less money. Seen four, (yes four) with broken puller jaws myself. Never seen a broken Tiger Tool although my #102 is getting to need a new pulling jaw. Some of those drivelines are TIGHT to get apart.

Lmackattack Posted April 12, 2018 Share Posted April 12, 2018 I hate the old style with the 4 caps that need to be pushed out. Some come out easy most are stubborn. the ones with the straps are way easy to remove and i feel they are less prone to damaging something when removing them 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53072-u-joint-with-4-capschange-out/#findComment-396429 Share on other sites More sharing options...

Maddog13407 Posted April 12, 2018 Share Posted April 12, 2018 those cast caps can be a pain in the ass to. pull a few hundred of the towin trucks and youll have your share of stubborn ones. have to get all four bolts started just right for them to start straight Quote Link to comment https://www.bigmacktrucks.com/topic/53072-u-joint-with-4-capschange-out/#findComment-396488 Share on other sites More sharing options...

Rob Posted April 12, 2018 Share Posted April 12, 2018 Doesn't look seated on the right land to me. Yoke stretch or spread can cause that. Don't like working with those too much either. I always take a 5" grinder with a twisted wire brush, (very stiff) and clean the ears and seating area of the caps well so the new joint aligns easier before drawing it down. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Hobert62 Posted April 13, 2018 Share Posted April 13, 2018 That's just the way the picture is. I was hooked up when I took it & was trying to avoid the grease on the front of the trailer.

Rob Posted April 14, 2018 Share Posted April 14, 2018 (edited) What you will see with wear, (and the angle of the photo appears to display) is the right side land for the joint, (looking from rear towards front) is a gap. All the torque is absorbed through the right side of the universal joint mounting flange. As those flanges wear or stretch, or twist, this happens and you usually here the damage as a "knock" in the driveline between upshifts sometimes but moreso as a knock when transitioning from forward to reverse, vice versa. Slips and spline wears sound similar but higher pitched usually.
