Jacking help removing rear axle

I'm removing the rear axle assembly to do some repairs on my Coupelet.

Does this look OK for balance?

The jack stands are just behind the door and just behind the gas tank.

They have to be outboard of the radius rods, this is as far back as I can get.

You can get them further back by first removing the radius rods and then proceeding. Apart from that, you really ought to use a stand with a larger footprint.

Looks a little teeter-tottery, but probably OK. it will get better once the rear axle is out.

When I removed the rear axle in Betsy to install her Ruckstell, I made a cross bar that spanned the rear frame rails and supported the car with it. If you decide to make a cross bar, make it beefier than mine, mine worked OK but was a bit saggy. :)

I remove my rear axle assemblies complete and place the jack stands right up tight to the radius rods BUT I do use the stands for my F-250 !

As long as the cat doesn’t jump on the back, you should be ok :shock:

I have mine about like Mark shows, borrowed the bar from a friend. Had the custom stands and elevation devices. :lol:

Jack stands too small
Not located far enough back, they can go back further, and should.

And now I see it's on a 2x8 spanning lift rails and on a lift!

Not a chance in hell that would be allowed on my property. Rethink this.

Thanks guys. I will look at removing the radius rods & move the stands back.

When I removed my rear end, I put the stands exactly where your's are. Didn't like it, no sir, not one bit. Long story short, I put a couple of safety stands at the junctions of the running boards, right where they meet the rear fenders. That's not a very strong point, but I rationalized that I was just trying to prevent tipping, while the main supports were beneath the frame proper.

As far as removing the radius rods before removing the axle/driveshaft, you might be able do that but you still need to have the radius rods fitted up to the axle and adjusted when you reinstall the whole assembly. Two reasons: (1) The driveshaft needs to be squared up perpendicular to the rear axle on assembly, and (2) On some cars the radius rods can't be installed once the axle is bolted up to the driveshaft.

I use a pair of these:

The tonnage is excessive but the dimensioning is ideal. They're also perfect if wanting to place outboard with a 6 x 6 across the back as others have mentioned. The price is very reasonable when weighed against the going rate for an ambulance ride.

Get some beefier stands and use a cross bar - worked for me. I rigged up a double support for my jack - lifted the rear end - backed up the jack with Jackstands while I removed the wheels - then used the jack to lift it high enough to get the rear end off and supported it with a piece of square steel tubing across the frame with hefty jackstands on either end. I was able to slide the steel tube between the frame and the radius rods so the rear end came off pretty easy. It ended up sitting that way for 6 months without issue.
First step - lift the rear end and remove the wheels.

I just did the rear end in my 26 roadster. I placed the jack stands as far back as I could to clear the radius arms. It worked fine.

If you jack up the rear end and remove the wheels you can put a piece of heavy wall steel rectangular tubing under the frame and over the wishbones and support it on good jack stands.

The key is to use a cross piece of hardwood which just fits up to the frame without hitting the splash panels. I use a 3 x 2" Jarrah beam. This allows you to move the stands much further back and wider apart, altogether a much safer situation. Then there is no need to remove the radius rods.
Hope this helps.

Chris that looks very close to the spot I used for my 26 Roadster. Maybe the lighter body makes a difference but mine was very stable.

"If you jack up the rear end and remove the wheels you can put a piece of heavy wall steel rectangular tubing under the frame and over the wishbones and support it on good jack stands."

I agree with you, Dale. And with all the others who advocate supporting the car with a beam at the aft end of the frame. I even had a beam that I could have used. But when I crawled under the car I discovered that the body hung below the frame a bit. So I would have been supporting the car on the edge of the body rather than on the frame. I considered putting some spacers on the frame to gain some clearance, but there were geometry problems that would have made for a somewhat precarious rig. In the end I decided that supporting directly on the frame was safer even if the supports had to be further forward.

Oh, did I mention that I put a 50 lb. shot bag on top of the radiator for good measure ?

Ever the coward,

Dick

If you want to support the frame with a bar across the frame like Dale, Dave and Mark. Check this iron out at your local Home Improvement Store. Less than $25. Strut bar is 1-5/8 in. x 10 ft 12-gauge material.

I used a 4x4 wood post 8 feet long from home dump, worked great. Why is it that when you do major work like this it looks like a bomb exploded around the T? There are tools and jack stands and parts everywhere while your working. I am usually too tired to clean up before the job is finished and it looks horrible when I come back the next day to finish. Some of you guys on the pictures look like you could eat off the floor, while working, and all tools and parts are in the neatest order than I can ever get. I used to be amazed at a mechanic friend of mine in the sixties, he looked like he wore his Sunday best while working on the dirtiest jobs and never had a speck of dirt or grease on him on the end of the day. I was always with best of luck, lol, if there was a painter across the street painting, I would have that paint on me by the end of the day, without ever going across the street. Go figure. We all have unique talents. Love the hobby. Frank

You don’t have to remove the rear radius rods, good balance is made on the frame as far forward as allowed.

Mine is done without a lift, but using safe high lift jack stands on the frame , these were US military surplus. Plus notice the yellow China stands there for added security anyway, they touch the running board brackets for peace of mind.

If you doubt you have adequate support, don’t proceed.

Well, everyone seems to have an opinion on this, so here's mine. With the engine in the car, there is no need to remove the radius rods and move the stands farther back. The only time this wouldn't work is when the engine was out of the car. I'll join in the chorus that advocates for better jack stands though. Goodyear Racing makes some nice ones which have a substantial base and also are tall enough that you don't need any additional blocks to lift them up higher. Mine are rated for 6 tons, which is obviously more than you need for a Model T, but they have a wide base and they extend to 24" height, which is perfect.

Hey Dan,

Got any pics of the lifting bars in use? I’m interested in where they go and what they rest on/against. And are they fastened to the car or just hooked into place and held by gravity and leverage?

Keep crankin’

I use the method first posted above by Mark. A six foot piece of 2" x 2" square tubing right in front of the rear spring works perfectly. I agree you want better stands. I use home made ones that are 27" tall, which gives me plenty of room.

You didn't ask this, but I'll mention that you don't need a spring spreader. Just loosen the rear perch nuts enough to relax the shackles. You don't even have to remove the perches.

Here's a video of the whole thing: https://www.youtube.com/watch?v=8mZzAt9Q_4k

Thanks for the pics Dan.

Would it be safe to put the ends of the straight bars on stands or are these lifting bars strictly an overhead hoist thing? Yes, I understand that ground support would get in the way of pulling the removed bits out from under the car, but I think that could be managed...

Personally, I prefer the overhead approach to rear axle removal. I built an overhead beam out of doubled 2x6s for my vintage chain fall. It could also serve for pulling the engine. Timber is handy and easy to make into needed garage items. The axle support on the floor jack is a 4x4 with appropriate additions.

Agree with Mike Walker that unless the engine is out of the car, there is no need to remove the radius rods. I use egg crates with a plywood topper to support jack stands. Done it literally a couple dozen times. Never an issue.
