27 buick rear axle play

Recommended Posts

Not being an expert of any kind on the subject, I am trying to figure it out.  The 1927 shop manual copy I have, talks about the play of the intermediate side differential gears (where the axle shafts are attached to) should be not more than .008" when assembled in the case.

 

There are adjustment sleeves for the bearings in the rear axle, but I think that has more to do with gear mesh.  But again, I'm not really sure, not having readjusted anything in the rear axle of my cars.

My axles have "some" end play, as seen when I jack up the rear wheel and move the wheel in and out toward the center of the car.

 

How much does yours have?

Forgot I had to measure end play with pinion gears in place. Now have .008 end play on each axle. On the inner axle nuts I have been using cotter pins put hard job cutting the right length as they interfere with the I guess you call it diffential spacer between inner axle nuts. Could I just use roll pins and red Lock-Tite. thanks for your help.

It seems like that would work, but if the roll pins ever did get loose it would cause damage for sure.

 

What size cotter pin do you need?

Your right, roll pin could slip out. I'll go back to cotter pins and red lock-tite on nut. Thanks
