Howard, I have some 4x4s. This is just a mock up in the pictures using scraps.

If I make another hook like the ones I used on the front bars (using all thread) and place the 4x4s where the 2x4s are in the image couldn't I raise the rear bar by passing the all thread through the 4x4 and simply tighten the nut to raise the bar.

This way I would not even require a jack

You probably could but one thing I would wonder about is the size of the hook and can you keep it from moving too far toward the seat end on the arm that it would interfere with the stirrup being swung into position.

It will be this weekend before I can try seating the load arms in the stir-ups again.

Got two questions for you.
Is there a certain type of grease that I should put into the seats before setting them in the load arms?

Also, what weight oil goes into the rear axle?

I'm sure all this is in the service manual but its been long day and I am just not in the mood to hunt for it.

Thanks.

Packard just says use the special lube in the seats which is probably the same as the special lube that was used in the compensator assy. Here is one O_D has mentioned on several occasions as a modern substitute.https://packardinfo.com/xoops/html/modules/newbb/viewtopic.php?post_id=156197#forumpost156197

Someone else will have a recommendation on the rear axle oil.

Stewart - Many of us use the 85W-140 GL-5 gear oil in our Packard differentials and transmissions. DO NOT use anything other than a GL-5 type oil in the differential. Any major brand should do. Some are rated for limited slip differentials, but they can be safely used in a conventional differential.

Progress on that rear load arm.

Back on post #184 I made some hooks to hold the front load arms. I welded a bolt on to a gate hinge to prevent the load arm from slipping off. I decided to put the pin back in place in the front so i could use the hook in the back end.

I tried it my way first by using the hook through a 4x4 to lift the rear load arm. I got the arm up about an inch pretty easy. Had to fight for the next half inch then the little bolt I welded onto the hook broke off and it slammed back down.

Instead of re-welding the bolt on and gave HH52's suggestion a try by using the chain and a jack. I was scared of it. It made some sounds I didn't like and the rear of the jack came off the ground but it worked. I raise the load arm up about 2 inches and got it seated.

I've not even looked at the other side yet. Will try it this week.

Thanks again Howard.

Great Job

Glad it worked out. Your jack looks a little shorter than mine so maybe that is why I don't have the rear lifting problem.. One thing on the next attempt might be to have the chain closer to the front wheels and fix it so it can't move. That way the rest of the weight being behind the chain should help keep the rear on the ground.

Nicely done Stewart.

Stewart,

Glad to know it worked for you.

With the frame on jack stands, I still wonder if you bolted the chain to the floor, (or ratchet strap the frame down), then used the jack to move the arm in place, if that would be safer.

The frame would be in a fixed position, and the arm would be the moveable part.

Still glad you got one side done.
