BucketTrucker688 Posted May 18, 2020 Share Posted May 18, 2020 I have a hub on my RD with 44k drive axles that will not seal. The spindle where the hub seal rides is semi pitted and I think is a major factor, does anyone make a wear sleeve and corresponding hub seal to renew the surface? Part numbers would be greatly appreciated if there is such a part for this. Allentown mack was no help to me, could not answer the question.

mrgumby Posted May 18, 2020 Share Posted May 18, 2020 Did you try the stemco grit guard seal 2 Quote Link to comment https://www.bigmacktrucks.com/topic/62583-44k-axle-spindle-wear-sleevedo-they-exist/#findComment-451466 Share on other sites More sharing options...

fjh Posted May 18, 2020 Share Posted May 18, 2020 How is the spot beneath the inner bearing for wear? The stemco idea is a good one however you need the proper install tools! Stemco makes a seal called a voyager seal it is similar to the scott seal and national seals thou! the other issue is the older 44s used to run a spacer behind the bearing may be an issue With the gritguard not sure I would clean the surface real well and install what you have with a skim of good quality silicone on the sealing surface clean and dri! all bets are off if the inner bearing is worn into the spindle!

BucketTrucker688 Posted May 18, 2020 Author Share Posted May 18, 2020 By eye the bearing wear seems to be ok, it's just where the seal rides seems to be pitted. I cleaned it up the best I could with some Emory paper and brake cleaner then a thin coat of some permatex gear lube silicone. And it still appears to be leaking, the hub looks fine and spindle look fine crack wise I was just thinking there's got to be a wear sleeve out there somewhere that should slide over the pitted part and leave me with a fresh new surface to seal to.

davehummell Posted May 18, 2020 Share Posted May 18, 2020 Call over to cooks and ask for tom or jeff they will fix you up with a seal and sleeve there has got to be some one near you that you could borrow a stemco sleeve installer just to drive the ring on. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/62583-44k-axle-spindle-wear-sleevedo-they-exist/#findComment-451474 Share on other sites More sharing options...
blackdog2 Posted May 18, 2020 Share Posted May 18, 2020 check vent to be clean also change spacer behind bearing ? Quote Ed Link to comment https://www.bigmacktrucks.com/topic/62583-44k-axle-spindle-wear-sleevedo-they-exist/#findComment-451475 Share on other sites More sharing options...
BucketTrucker688 Posted May 18, 2020 Author Share Posted May 18, 2020 Just cleaned the vent, I actually changed the vents over to a Spicer vent with the preformed rubber tube. I donth think there's a spacer anywhere. Unless your talking about the bearing race?

BucketTrucker688 Posted May 18, 2020 Author Share Posted May 18, 2020 One of the parts stores around here are telling me to use a scottseal xl +. No special tools needed to install and will seal better than a stemco grit guard. Any input?Sent from my Pixel 3 XL using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/62583-44k-axle-spindle-wear-sleevedo-they-exist/#findComment-451484 Share on other sites More sharing options...

Sent from my Pixel 3 XL using Tapatalk I agree with them how ever you seem positive it’s leaking at the seal where it meets the spindle! As stated make sure it’s not cracked! I would still use the scot over stemo and good quality silicone on the pitted surface clean and dry also check you diff vent for being pluged Quote Link to comment https://www.bigmacktrucks.com/topic/62583-44k-axle-spindle-wear-sleevedo-they-exist/#findComment-451510 Share on other sites More sharing options...
Ezrider Posted May 19, 2020 Share Posted May 19, 2020 i generally use the 2pc seals for trouble wheel seals as well. installation is easier than the sleeves and no special tools and they work good.

BucketTrucker688 Posted May 21, 2020 Author Share Posted May 21, 2020 I just took it apart again and it looks like the seal is dry from the outside and the underside of the axle tube (to the inside of the spindle) is leaking directly under the brake shoes. Is there a fix to this or does the whole axle housing need to be replaced? It doesn't appear to be cracked but it's very wet all on the bottom of the tube.

Ctaxle Posted June 4, 2020 Share Posted June 4, 2020 bucket trucker, yes i have seen this before. Macks were prone to cracking at the factory friction weld.
