mowerman Posted March 29, 2022 Share Posted March 29, 2022 Well I would for sure feel more comfortable with a new axle especially if your going to load it heavy most of the time ….

Tinman22 Posted March 29, 2022 Author Share Posted March 29, 2022 (edited) Same here. axle surgeons should be here anytime. When I get it off i'll cut it in half lengthwise just so we can see if i was right.

Steve L Posted March 30, 2022 Share Posted March 30, 2022 Shocks on 38s are fairly common here in Oz. Looking at the axle pic welding a new stub on this way is not safe as I have seen these break off along side the weld. Also unless the whole axle is put in a lathe they can’t be straight causing excessive wear on planetary gears and axle shafts especially the 44 floating shafts ( the axles with splines on each end ) Is it not possible to purchase the original stub / quill from Mack’s? They’re simple to fit, should be 100% straight and not subject to crystallisation due to excessive heat concentration by welding.

Tinman22 Posted March 30, 2022 Author Share Posted March 30, 2022 Hmm. guess i should have kept the 4" badly welded stub that everybody said they would run. The original was friction welded so no sleeve fit either. springs are 4003a's bearing surfaces on all four are 3.25 inner 3.00 outer with 2.27 id tubes with stamped housings. guess ill just keep my fingers crossed. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69422-axle-repair/page/2/#findComment-493794 Share on other sites More sharing options...

I originally said no way in hell would I run that if it was just a "new" spindle butt welded in place, which it sounds like what you are saying was the case.

Tinman22 Posted March 30, 2022 Author Share Posted March 30, 2022 Sorry i said everyone as that was not the case. I did have quite a few people say the would run it though. The original spindle was a friction/butt weld. nobody had or even offered a press in spindle As far as straight well its not. It seems to be measuring out .010 ish pointed down and square L/R. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69422-axle-repair/page/2/#findComment-493798 Share on other sites More sharing options...
doubleclutchinweasel Posted March 30, 2022 Share Posted March 30, 2022 Remember, they are ALL welded together somewhere! Sounds like you had a good, professional repair done. Having both bearings on the new stub should be better than the "split between the bearings" setup. The original patch...not so much! 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Tinman22 Posted March 30, 2022 Author Share Posted March 30, 2022 That spindle is hanging on the wall of shame. I do agree steve l. a pressed in spindle is what I wanted but apparently not available and after it was cut just inboard of the spin weld It became apparent why. Where the original housing goes from square to round is only about 4" deep. The transition from sq. to rd. takes about 1 7/8" leaving approx. 2 1/8 of clean round tube. In my opinion any insert is better than none but the axle fixer people apparently disagree. I guess time will tell. Maybe ill take a housing from the 94" r when it gets converted over to air ride and use it on this truck. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69422-axle-repair/page/2/#findComment-493805 Share on other sites More sharing options...

Tinman22 Posted March 30, 2022 Author Share Posted March 30, 2022 Maybe i'm as my wife says "just being me". I don't like vague or questionable. I like definitive. My jeep 6 died so it got a 440/727/dana300/dana60/14 bolt driveline. Its never left me walking. Given the original assembly was spin welded and it seems to have all the innerds that make up 44k axles (at least according to mack) and it is definitely better than the trail fix it had before so I'll run it. My 94' has a bad trunion and We were going to make it air ride so maybe i'll use a housing from that if they are the same. Still better than it was.

mrsmackpaul Posted March 30, 2022 Share Posted March 30, 2022 Well I reckon you've done well You'll no longer be guessing and wondering and should be good for ever Happy days I reckon It is funny how sometimes you just cant win on social media lol As long as your happy that is all that matters The original repair might have been done by a professional and the ability to align things on the truck might not of been as accurate years ago as it is today Great stuff Paul Quote Link to comment https://www.bigmacktrucks.com/topic/69422-axle-repair/page/2/#findComment-493816 Share on other sites More sharing options...
