How far do I need to pull out the axle shafts to be able to remove the third member?

I'll be going to my local auto shop to "Loan A Tool" to borrow the axle remover / slide hammer this weekend.

I'll be Frank, this hobby isn't getting any easier.

About 12" will do.

As soon as you feel them drop into the axle tube.

Thanks folks.


I just hope they are not stuck in there good.

If they are stuck I can give you a couple options to try. First try to spray the bearings where they fit into the housings any way you can with PB Blaster or your favorite PENETRATING oil not WD40 after removing the 4 bolts that hold the bearing retainer plate and working it free. Grab an old brake drum and put it on the studs backwards put all five lug nuts on til the studs are about level with the lug nuts then push the drum against the flange and YANK on it several times til the axle starts moving (same purpose as the slide hammer) If it still will not budge snug up the lugs with the drum still on backwards and get your BFH and give the drum a good whack rotate 90* repeat, repeat, repeat see if it starts moving. If those fail then take a long drift small enough to go through the bearing retainer hole but still a solid piece of steel and do the same thing hammer the drift against the back of the axle flange, whack, rotate 90*, whack, rotate 90* eventually it will move. If you cannot find a drift small enough you can remove the ebrake cable (use a small hose clamp around the fingers of the ebrake cable to slightly compress them to get it out of the hole in the backing plate without destroying the cable) and use a LONG 3/8 drive extension to do the same except you have to keep it at an awkward angle but it will work.

Keep small children away as usually lots of cussing will be involved.

PS If you change the bearings do NOT forget to put the bearing retainers on before you put the new bearings on the axles.

ragtp66,
I did try the drum on backwards but no luck. PB blaster also.
No luck loaning the slide hammer from the local auto shop as a previous person broke it and they never replaced it in their inventory.

I went ahead and ordered me a kit from Amazon. I'll wait till that comes in and hope to get around to it next weekend.

Only pulling them far enough out to check the gears. If they are numerically higher than what I have in my other diff, I'll swap them out.

I'll be Frank, this hobby isn't getting any easier.

Can’t you check the gear ratio without pulling the axles?

A method I used that never failed. Get a piece of heavy chain about 10 ft long. Attach one end with a washer and nut to an axle stud. Pass the other end through a concrete block and then to another stud. Give the block a heave. The axle WILL come out!

IT IS NOT NECESSARY TO PULL THE AXLES TO DETERMINE THE GEAR RATIO!!!!!!!!!!!!!!!!!!

This I know but I want to compare the gears to the gears in the diff I cleaned up.

Then that will require pulling the axles and removing the center section, which really is not too difficult to do. There was once a day (back during the Civil war days) when I could swap center sections in 45min!!!
