Preservation of a 68 Camaro

I think it also doesn't like oil, it will shorten its working life.

[cook_dw]

Correct.  Any grease, oil or petroleum product will decrease the life.

Finally got more Evapo in.  Soaked the backing plates and axles.

Photo 973 - 2 steps forward 3 steps back.  A reminder when rebuilding a diff, remember to put sealant on the splines and threads of pinion when installing the yoke.  If you don't you might have the same issue I just had.  Leaking oil through splines and around nut.  Blessing in disguise I guess.  I want to replace the nut any way.  I was able to save the gear lube and GM limited slip lube.

 I'd gotten in a rush when I pulled the yoke back off the first time (using a solid sleeve I left the rear seal out until I got the setup where I liked it) to install the seal and just slapped it back together without blinking.  Guess I'm getting old and forgetful..  Either way yoke was pulled and cleaned (along with the splines) I used Ultra Black and applied to the yoke splines and a helping on the washer face.  Let it dry overnight and I'll fill'er up and see if it leaks now..  Then its axles and back under the car.  Also replaced the nut with the original.  The one in the Yukon kit I had was not satisfactory for me.

Looks like new.

After letting the Ultra Black setup I added some Penn Grade 1 80w-90 (formerly Brad Penn oil) along with GM additive.  Let it sit for about 30 minutes with the carrier facing upward and no leaks.  Next was throwing the axles in with the c-clips and installing the carrier pin and finally buttoning up the diff cover.  Also dug out one of my NOS diff gaskets.

One thing I forgot to mention.  I also took a file to the mating surfaces on the cover and housing.  Applied a thin coat of Ultra Black on the housing, placed the gasket and then applied a coat on the cover.  Cross-pattern on the bolts and good to go.

This would make a great book.

Ha!  If anyone wants to do the writing; I'd supply the photos & processes.  Too much work for me to do but I appreciate the comment.   




No real updates.  Photo of the traction bars I plan to use.  I need to get them blasted and prepped for paint.  I guess I'm making myself a liar as I will have a "restored" part on the car.  Eh, nobody's perfect.   


Photos 983 - 984 - Square tube early Lakewood bars.  Note that the pass side bar is slighlty longer than the driver.  Yes they were designed & made this way on purpose.
