Jul 21st, 2025 | | | | Joined: May 2005 Posts: 235 Shop Shark | | Shop Shark Joined: May 2005 Posts: 235 | I was adjusting the brakes on the truck last night trying to make preparations to hit the road for Denver tomorrow morning when I noticed the left front wheel bearing sounds like crap. Trying to find the correct wheel bearings for a 50 1 ton without sending stuff back. I seem to remember a B24 B25 number but I can't find them in my notes and All I can find is a 53-59 Application Suggestions would be really great right now... Indeed to get out of here. Jeremy | | | | | Joined: Mar 2004 Posts: 873 Shop Shark | | Shop Shark Joined: Mar 2004 Posts: 873 | The spindle and bearing ID sizes changed in '53 when the new Bendix brakes were introduced. So, to answer your question
the '53-'59 bearings will not work on your '50 spindles.
Hope you can find some for your trip. | | | | | Joined: Sep 2001 Posts: 29,262 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,262 | Yes, there are different 1-ton spindles between 1947-1955 (the question in your title). Here is information on front wheel bearing compatibility/differences. | | | | | Joined: May 2005 Posts: 235 Shop Shark | | Shop Shark Joined: May 2005 Posts: 235 | Tim,
Does that info translate as:
1950 inner front 909026 (ND909526, ND909626, ND909726)
Which, if I recall, translates to the Bower B26 number.
1950 outer front 909025 (ND909525, ND909625, ND909725)
Again translating to the Bower B25 number.
Does this ring a bell for anyone?

Front (original) wheel bearings for 3/4 and 1 ton Chevy.
Bearing # ---- Bore --- O.D. ----- Overall Width --- Outer ring Width --- Inner ring Width-
'53 to '59
B-46 ------- 1.4995 --- 3.1500 ---- 1.2360 ----------------- .8510 --------------- .9170
B-45 -------- .9058 ---- 2.2503 ---- .8000 ------------------ .6900 --------------- .6590
'46 to '52
B-26 ------- 1.4060 --- 3.1500 ---- 1.2260 ----------------- .8510 --------------- .9170
B-25 -------- .8435 ---- 2.2503 ---- .8000 -------------------.6900 --------------- .6590 On the Classic Truck Parts site looks like BR2706-R inner set and BR2716-R outer set are what I'd need for 53-59 1 ton roller bearing conversion Also check this post with a possible way to use new roller bearings not already mentioned. https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=629388#Post629388Grigg | | | | | Joined: May 2005 Posts: 235 Shop Shark | | Shop Shark Joined: May 2005 Posts: 235 | Soooo I gave our bearin distributor 4 timken part #'s on Tuesday, he sd they'd be here today. Got a message they were in and when I went to pick them up there were 2 parts! One complete bearing!
Aaaarrrrrrgggggghhhh!!!
The part numbers I came up with are:
# Bore. OD. Width
Hm88648. 1.4062 2.875 1.063
Hm88613 (cup)
M12649. .8437 1.9687 .690
M12610 (cup)
I had planned on pressing a fit sleeve on the cups to bring them up to the required OD.
Now I'm stuck looking for the bearings. Looks like I'm missing bonneville.... That sucks. | | |
