mrsmackpaul Posted July 19 Share Posted July 19 I still have a few Probar axles, very simple and well thought out axle One tool for the nut and for the cap, one spilt pin holds the whole show together Square axle that mounts easily on the springs and spring purchase Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74351-identifying-a-trailer-axle/page/2/#findComment-555532 Share on other sites More sharing options...
Joey Mack Posted July 19 Share Posted July 19 I took care of a fleet, that had 6 or so with propar, fruehoff, axles, had to keep the bearings in order when putting them back in during a wheel seal repair,since they were the same.. seal # 370065-A, I liked the screw on axle caps too, that some of them had.

seyser Posted July 19 Author Share Posted July 19 (edited) Just want to confirm these parts: Seal: 370025A Shoes: 4515Q 16.5x7 Drums: Anyone able to tell what size the drum is or do I have to remove them and get a measurement? I will check with my parts stores but sometimes like to order online as to get a better quality part the my local jobber stacks. I cant speak for commercial vehicles but seems like everything at my local automobile parts store is china made and I try hard not to support that. Thanks everyone for the help.

Joey Mack Posted July 19 Share Posted July 19 996 B is a strong possibility, im forgeting 2 other drum numbers, make sure the drum is piloted by the axle hub. Thats what keeps it true. The drum number is cast into the drum Quote Link to comment https://www.bigmacktrucks.com/topic/74351-identifying-a-trailer-axle/page/2/#findComment-555543 Share on other sites More sharing options...
Geoff Weeks Posted July 19 Share Posted July 19 You really can't tell what drum you need without pulling the wheels and looking. There are some real popular ones, and if it had hub pilot wheels it would be a fair guess, but with stud pilot, and not knowing even if it is inboard oi outboard drums, there are just too many possibilities.

mrsmackpaul Posted July 19 Share Posted July 19 Most drums have part numbers cast into them They also normally have the maximum wear diameter cast into them So maybe drop some wheels off and have a look is the best option Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74351-identifying-a-trailer-axle/page/2/#findComment-555551 Share on other sites More sharing options...
