I am finally putting together a Dana 60 for my charger out of a truck and I finally got my tubes cut and new ends welded on so I brought it to my guy to fix the gears and he called me and said the pinion bearing race has .009 clearance and it looks similar the race spun in the instance. I was told JB weld the race in but the guy setting information technology up said he didn't actually want to do information technology that way. He said he establish a race with the same inside measurement and a lilliputian larger on the outside and can have a guy motorcar the housing for the larger race. Going to cost me $200 to have it machined to fit the new race. Seems like this would be a better fashion to practice the chore correctly. What does Moparts think?

Spend the Money and prepare information technology correct...JB weld is NOT the respond.(seldom is)
which of the two pinion bearings is it?

Theres a lot of force on the pinion race and bearing. You want that to remain as truthful equally possible to go on pinion gear deflection downwardly every bit low as possible. .010 is to much slop and JB weld volition be to Soft of fix. Fine maybe for a street car, and I mean Street as in merely a driver.

But for a performance build do the right fix. Also, how are the carrier races, seen them egg shaped and diddled out.

I would say have it done, you got time and money in it now ,why junk it when it is salvageable and nobody will e'er know.

Spend the coin and ready it right, JB weld is not the fix.

With that much clearance I'm going to approximate y'all bought this housing stripped downwardly already , otherwise that bearing race would have just fallen out of the example when you lot flipped it over to remove it.



running up my post count some more .

I say fix it right. If it spins, gets hot, and locks up the rearend at speed it will exist money well spent. Things tin can become UGLY existent fast.

Machining the housing IS the right way to fix it. Get the part number of the new bearing so that if you need one downwards the route, you will have a reference.

I'thousand betting the other way. Well-nigh machine shops at present can get the tolerances closer than that factories did 30 years ago. These machines in the right hands are crazy accurate. Mayhap that's why it spun.

I am having information technology machined. Hopefully information technology's done correctly. I accept to much in to the housing already having the main caps fitted and having information technology narrowed and welded. The guy setting information technology upwards really stressed on the force on the bearing and race was to much in a race auto for jb weld.

Indexing for the proper eye isn't a problem these days. No dissimilar than a proper line bore, lifter indexing or whatever other block work, just on a smaller piece.

Indexing for the proper center isn't a problem these days. No different than a proper line bore, lifter indexing or any other block piece of work, just on a smaller slice.

How proficient were these housings machined back so? I would say at that place was a expert deal of tolerance on a mass produced housing anyway. Be a good time to really blueprint that housing to exact specs.

Indexing for the proper middle isn't a problem these days. No different than a proper line diameter, lifter indexing or whatsoever other block work, only on a smaller slice.

How good were these housings machined back so? I would say there was a proficient deal of tolerance on a mass produced housing anyway. Be a skillful time to really blueprint that housing to verbal specs.

The Dana housing that I congenital for the Ramcharger had that issue and it was machined by the differential shop that assembled that one with the spool. They do a lot of race car diffs.

The Dana that I built for the Daily Driver had already been overhauled properly so all I had to do in that location was to cut one tube and shorten and respline 1 axle. All the bearings and brakes were new and it came with four.10s and a PowerLock.

The guy I have set up my gears is very picky about his piece of work and doesnt want me to take a problem down the road. I looked into all the different loctite race adhesives and primers. I also talked to a very reputable person on here and they said to just used JB weld put some on both mating surfaces of the race and housing and I wouldn't accept any problems. The new race is coming on Friday and hopefully it volition be done by the end of the weekend.
