Did the search:flipoff2: major brain overload. Does any body know the Timken part numbers for Bronco Rotors going on 77 Wagoneer spindles?

rotors you can get at carquest or whatever. I assume you mean the wheel hub, if so, it's a dana part not timken. What are you really looking for?

On my old 74 waggy, I used 83 bronco rotors, hubs & hub seals. The bearings from the waggy hub worked in the ford hub.

I'm with Aggro on this..I dunno WTF you are asking either. But I figured that I posted enough info to get you going.

If you're looking for bearing numbers, the Ford hubs use BR35 outer and BR37 inner, but the Wagoneer spindles may have gone to the larger inside bore inside bearing like Chevy did, if so, you'll need either early Chevy (67-73) spindles or later Ford TTB spindles to use your six bolt knuckles and GM or Jeep brake hardware. I run '78 Bronco hubs and rotors on early Chevy spindles (that will soon be replaced with Ford TTB ones) with early Chevy flat-top kuckles and Chevy caliper mounts. You could use Ford stuff from the knuckles out, but then you'd have the three bolt spindle and those stupid wedge style calipers.

The year split is later than 73. It is more like 77 or 78.

Get a micrometer. The inner bearing surface on the spindle needs to be about 1.440 or something in diameter - if it's 1.550 or so, you need an earlier spindle. Go get the BR37 and measure the inside surface - this is what needs to get accomodated.

Finally, SEARRRRRRRRRCCCCCCCCCCCHHHHHHHHHHHHHH.

Good luck
Bob

The year split is '77 for Chevy Dana 44 vs. Corp 10 bolt, but the Dana 44 used the same large inner bearing spindle after '73 or so, at least in the 8-luggers. The old external Dana 44HD hubs use the large inner, but I'm not sure on the 1/2 ton stuff. I know my buddy's '73 1/2 ton had the early spindles, but I have a '74 3/4 ton with the large bearing spindles.

why are you going with the TTB stuff just out of curiosity? is it stronger than the chevy?

No, the TTB spindle uses the same bearing as the Ford 5 on 5.5 hubs, but has a six bolt flange like the Chevy or Jeep 44, so you can use the Chevy or Jeep caliper mount and bolt on calipers, rather than the Ford wedge style. The Chevy spindles that use the smaller inner bearing like the Ford are hard to come by. Plus the Chevy flat-top knuckles are easier to find in my neck of the woods, and I'm an old Chevy guy anyway.

Ok sorry if I was not clear. All I need are the bearing part numbers. I allready have small spindles off of a Wagoneer, new 77 bronco rotors from Kragen. The new rotors only have the races.
I am a firm believer in only useing Timken bearings and can get them through work, in the past I have used part numbers that start with "LM"and a whole bunch of nubers after that, but that is a different front end.
I do not understand what a BR35 and a BR37? I did find a write up by Belavista and he mentions a set 37 and a set 45 for bearing part numbers. They are close to the numbers 4Bangler gave but which are correct?
Does Set or BR mean it is the bearing and race.

And Trango I did search as I said.

ok, so you're using the TTB spindle, but using the chevy (or jeep) caliper brackets and calipers right? does it matter what year they are, like do they have to match the year knuckle you are using? also, now that you are using the ford spindle, are you using the chevy outers or the ford outers? cause aren't the ford outers a little bit shorter than the chevys?

No No
All small bearing Wagoneer except the Rotors which are Bronco to get the 5 on 5-1/2

i meant 4bangler sorry haha should have been more clear

I assume that when you say your 77 Ford rotors only have the races on them you mean that the hubs still have the old races in them. You're right about the Timken bearing numbers starting with LM.... I used to know them, and if I was a home (I work 250 miles away) I could give you the number. The BR35 and BR37 are Federal Mogul numbers that are also used by CR and almost everybody else, and if you go to a parts place and get those bearings, open up the box and read the number off the race, should be the same as the Timken #. Or you could knock out the races out of your hubs, you'll need to do that anyway, and read teh number off those, as long as they haven't spun, but then your hub would be junk. I know that the inside bearing is available with three different thickness races, but I think you should be able to get the right one, the others aren't very common.

The Chevy and Jeep calipers and caliper brackets are all the same and will all interchange. The only ones that are different are the 3/4 ton ones that are a lager diameter to allow the use of larger rotors. Some guys like the full circle thick steel caliper plates, some like the ones that are half tin, they leave the tin off so they can clean their brakes easier. I'm running the Jeep (same as Chevy) outer axle shafts, the Fords are a little shorter, but I haven't noticed a problem. The shorter stub shaft may help hold the lockout tighter to the hub, I have some Ford outers and will prolly run them when I get around to it.

Timken numbers according to Autozone. Set37 and set45. Those are the bearing numbers for pre-77 Chevy spindles and for Ford spindles.

OK.

The Ford TTB spindle will NOT work. I have both 76 Chevy and Ford TTB D44 spindles and they are different lengths, because of the difference between the Ford caliper mount cast into the outer knuckle, and the Chevy/Jeep one bolting on over the spindle.

Pic on my site of the 2 side by side. TRUST me on this.

For bearings and number interchange go to www.timkeninfo.com. You can punch in an app (like 76 Chevy K10 pickup) and get the partnumbers. Or click on "interchange" and punch in another manufacturers part number and get a cross reference to Timken, and a bunch of other part numbers that match.

Also - some of the above info on when chevy switched from small to large inner wheel bearing is wrong. Info should all be on my page

No I said new hubs that came with new races.

BillaVista, the Link for timken is dead.

It's just overpunctuated.

http://www.timkeninfo.com/

Ditto about what BillaVista said about the TTB spindles. You need 1.5 inches of offset before the inner bearing surface, and the TTB spindles only had 1". I had one entire hub bolted on, ready to go, with those TTB spindles, and then I tried to bolt the caliper onto the brake bracket (which also has to be from an early chevy or waggy). It didn't line up - AT ALL. Well, it did, it was just .5" off.

I almost fawkin lost it, since I was deadly frustrated - almost as much as I was when I snapped the ARB hardline in the diff (another story for another time). Had I known this was your application, Aaron, I would have steered you away from this. Sorry.

Cheers
Bob
