Slide hammer alternative

[Kaizen]

I have a pontiac 10 bolt rear end about 1970 that i'm tearing down. This is NOT a c clip rear end. I've taken off the four bolts at the mounting flange and understand i'm supposed to use a slide hammer to pull it out. I do not have one and not keen on shopping right now due to the virus. I do not have a disc caliper so can't use that trick.
Will putting wedges between the tube and backing plate or such work?
Heat something?
Weld a piece of steel to a lug nut with a T on it and hit it with a hammer?

Your last sentence I wouldn't try.
It needs to come straight out. Hammering on 1 stud at a time will probably cause it to bind in there.

Heat helps alot of things, but of course it kills seals and bearings.

Best of luck!

Do you have a brake drum or tire rim you can slide over the lug studs, thread on the nuts and use it moderately as a slap hammer?

Do you have anything heavy made of steel - like a set of weights for barbells? You could make a puller with a plate of steel, and a couple pieces of rebar. Frankly I would go get a bottle of 70% alcohol, a mask, a set of rubber gloves and go over to Harbor Freight. Put the alcohol all over the package of the puller when you leave, on the rubber gloves and pour some on the ground to run your shoes in. Pour some on the mask and take the gloves off and toss them. You'll be fine.

Also - is this the style where the plate holds the axle in and once the bolts are pulled the bearing comes out with the axle to be pressed off, a collar is broken with a chisel or dremel, and then a new bearing is pressed on with a new collar, or is it the style where the bearing is just pressed onto the axle but the forged flange has to be pulled off first with a special gear puller like Dana CJ7 axles? Some axles are held in with a clip inside the differential too.

perhaps make your own slide hammer. Something like threaded rod with the head of a sledge hammer, lifting weights etc for the slide.

 

[MBfreak]

Bolt up a contraption and a rod. Use a heavy piece of steel sliding over the rod.
After all , we are GJers and always find ways.

Most auto parts stores should have these available as a free loaner tool.

All the auto parts stores in my area are still open.

I have no idea. Never dealt with this before. Assuming from my reading it just gets pulled out. How would it get pressed out? Here is the end with plate removed.

I’m sure. Don’t want my final thoughts as I drown in my own fluid to be “all for a slide hammer”. I have done plenty of risky things but this just ain’t worth it

A long chain , across two lug nuts . Whip the chain , should pull it out.

so put chain links over studs, add lug nuts, and whip it? i hit this pretty hard. its not budging but i'll try it.

 

[lostmind]

Yes , works for me

Yep, Done it many times, but never two lug nuts. Just one. Trick is to get just the right amount of slack in the chain to provide the right pull/jerk. Whip chain and jerk the slack out near simultaneously. You'll feel it when it's right.

 

[finn]

A chain and your spare tire and wheel will work surprisingly well.

Thread a link of a chain, about 4-6 feel long through a wheel stud, install the lug nut, attach the other end of the chain to the wheel (can’t remember exactly how I did that, but likely looped the chain around the tire and threw the center, and used a bolt , nut, and washer)

Allow some slack in the chain and “let er rip”.

The momentum of the rolling wheel and tire will pop tha axle shaft loose after a couple of increasingly violent attempts.

Buy a cheap slide hammer kit. It's not a precision tool. Makes life easy. You'll use it for other jobs too.

Kaizen - Amazon has a bunch of different slide hammers available. It might take a couple of extra days to get there, but it would keep you from risking exposure. I've had to slow down a few projects in the shop for the same reason. I've been ordering stuff that I normally would have just bought locally. Just a thought. Stay safe (both with the virus, and the redneck engineering attempts) and good luck!

yea good idea. still waiting to see if anyone can tell me if this does have to be pressed out and back in. Might not even want to deal with it as i have another with the clip. that one came apart in ten minutes.

Do you know exactly what it came out of ? I have a customer who is pretty much all Pontiac and I can ask him. I am pretty sure it should just slide out other than the 50 years of crud holding the bearing into the end of the housing.

 

[rlitman]

Well, Kaizen asked about welding something, so making a slide hammer shouldn't be too hard. When my 2lb slide hammer wouldn't budge one of my half-axles, I made a 10lb one using a cast iron weight plate as the slide, and a scrap rod from a hammer drill, welding a scrap lug stud on the end to hammer against.

 

[r00a005]

If it has no c-clip, it doesn’t need to be pressed in. (Or out). Maybe the bearing has spun in the race. I have had to tap them out before with a sledge.

 

[engineer2]

These have the bearing and seal press fit into the housing. It's not a tight press fit, but rust and crud can make them harder to pull out. I've used a cheap Harbor Freight slide hammer kit. HF used to sell them, but don't see them on their website. There are usually some on CL, or as said, borrow a kit from the parts store. The chain trick sounds interesting and should work.

 

[jimindm]

The bearing have to be pressed on the axle shafts.

You could try the chain trick. I have seen it work.

You could take some threaded rod and a coupler nut and sort of press the axles apart.

Come to think about it a port a power with the wedge adapter might also work.

 

[engineer2]

True. Once you get he axle out you still have the fun of pressing the bearings off. Auto parts store used to provide this service. Not sure if they still do.

Chain trick didn’t work but the portapower got me thinking. Used a socket against the end of the axle and a pry bar. Got it moving and used a deep socket with the pry bar and they popped out and got them out. Thanks for all the help. Ugly. Housing was less pitted so thought I’d use this but not sure now.

The bearing gets pressed on and off the axle, it's just a very snug fit in the axle tube.

With it on the car I could usually just turn the brake drum around put a couple nuts on loosely and use it as a slide hammer to pull it out.

 

[SGKent]

some axles have a collar that goes on behind the bearing to hold it. You hit it with a chisel to break it, then to add the new collar after you press the new bearing on you heat the collar, slide it on, press it to be sure it is seated, and let it cool. Don't know about Pontiac. Do know that one time I was pressing a bearing off an axle, and the lip of the flange caught on the press without me seeing it. When the axle kicked out it under load from the press, it not only bent but I imagine it was like someone might feel being kicked in the stomach by a horse.

 

[Spareparts]

That is why the old 12 bolt GM's were not good for circle track racing, the axle breaks and the axle, brake drum and tire and wheel came out and went who knows where, they made plates to hold them finally but the 9" ford became very popular.

 

[gearhead1]

I also used the chain across the studs method.

 

[Shadowdog500]

Do this easy trick and it will be off in a few minutes.

Skip to 2:55 in the video to get to the meat of the video.

Effectively you put the rotor on backwards and thread the lug nuts onto the lugs a few turns. Then you use the rotor as a slide hammer.

Nice job. That axle is a nasty mess, though!

Yea going on the scrap pile. If the axle was like this who knows the abuse it saw. Did have big gears in it compared to the Chevy ten bolt. Going to measure them up to figure the ratios as a learning experience.
