9 inch Big Bearing issues

[ENDLIFE]

I would first identify if you have a medium duty large bearing, or a regular large bearing rear axle (same bearing). I would use a decent set of calipers or micrometer to verify the size of the bearings you have and the axle orifices. Once done with all these steps I would make the decision to replace the housing, or to cut off the ends and weld on new axle ends. .008 is WAY too much clearance for a bearing location fit, and should be addressed as soon as possible.

They have to be somewhat of a loose fit or you wouldn't be able to get them in or out.

What he says is correct

OK, I went to the local autoparts store and picked up a set of bearings and seals. The bearings they handed me were much smaller that what I have (2.75" OD approx). They went back to the book and came up with the 88128R8 Large Bearing which was 3.125 x 1.50 which is what I have. They had two rear axles listed 2345 lbs and 3300lbs, and mine turned out to be the 3300lbs axle.

I slipped the new bearing in the housing and it measured .006 gap. My buddy at the local buggy shop suggested that I get a cheap set of feeler gauges and cram a couple of small (002) feeler gauges in there and butten it up? Hookey but it might work.

I did call Currie and they will sell me a Torino housing with axles, bearings, and disk brakes for $1,400. Not cheap, but it will give me a new rear end with disks and ebrake. Hum

I would only hope that they would have noticed that they were different lengths.

The gap in Photo 7 will only get bigger because the bearing will move and overtime will oblong the bearing cup. My 74 started leaking because the gap got so large the axle seal was being deformed. The gap was so big I had to shim it with pig putty and strips of beer cans. I did this as a temp fix. It's been holding for a year now but I wouldn't recommend doing it. I was quoted $350 to get the cup/end replaced.
