Trying to Convert R model to Hub Pilot

Recommended Posts

I'm wanting to change my steer axle on my 88 R model to Hub Pilot. I called local parts dealer Traction and they say it won't convert. I then called local Mack dealer and they told me same thing. I'm hoping someone has had some luck with this and would appreciate any input before I give up hope. My front hubs are 89032-R

I know a guy that converted a 66 R model to hub pilot. If nobody on here has better answer I can get ahold of him and see where he got his parts at for you

google gunite, it will take you to accuride and go to KIC hub assy and put in your cup numbers in your old hub and you can see if it will convert.  Post your VIN or model and last six of VIN if nothing has been changed and I will see what I can find.

I called Global talked to Don he was extremely helpful. He said they don't ship to Canada but was good enough to give me parts numbers I needed. Steer axle hubs are 10082201 Conmet brand. I was able to order them from local parts place along with drums and shoes.

Old style stud pilot parts are harder to come by and more expensive here. Stud pilot drums are $500  hub pilot are $150 for extra cost to change hubs it pays for itself in long run. Also my old rims are approx 30 years old I can upgrade those as well for safety reasons.

You are not kidding about the front drums.

I priced some front stud pilot drums and they were about 5 bills, ended up finding a set of nice used ones

Thanks for the info Superdog I'm gonna order new for front and see if I happen to find a used set at wreckers later. Around here it's not easy to find any at wreckers unless you happen to be there and find them yourself.

A used set for my drives I mean. I'd eventually like to do complete truck.

I was getting bad mileage out of my steer tyres. Would be flat out getting 80,000kms from them and that was pushing it. Rotated them every time I serviced it. 

I replaced the rims and straight away I’m up to 120,000km. 

I’d be interested to see if you get better wear with the new rims.
