Here i try to show how to replace a drive axle bearing with only simple hand tools. The drive axle is from a 1970 Dodge 8 3/4. The bearing is replaced wit a Green bearing for a Dana 60 application but the procedure is the same and can perhaps be used on other axles with same solution.

Thanks! I needed to do this job exactly like you showed it because I have no special tools.

I didnt use any heat on the first race, i barely got it to break free, the second one i put some heat on it and just a few taps and it came right off, had my 10 ton press to put new ones on like butter, thanks for the video sir

Great video. I grew up doing this when rebuilding axels. You can get the pipe longer than your axel then thread an end cap on it. Helps when hammering away on it so the end doesn’t flair out.

Hey if your axle shaft seal was leaking, its usually caused by the seal retaining plate being bent on the seals surface. Heat up the plate with torch lightly and set retaining plate on table after removing bearing and lock collar ring and lightly tap the rim surface of plate with a small flat sludge until its flate all the way around rim. Change bearings and seals and locking collars and you wont have another Axle leak! But if your plate is slightly bent and you reuse plate without straightening the rim, you can get leaks just 2-4 months after replacing bearings.

Last night I put the axle is the chest freezer and heated the bearing to 250F. It slid right on with no press and no pipe.

Thank you for this comment. For sure a good method. At my place it would come to the negotiation wether the freezer is available as garage equipmen. But of course, over night could be a solutio 😁

@ifixmycarmyself2502 2 жыл бұрын
Yes, was hoping so, especially fir those who has not access to a press. The pipe is 42mm internal dismeter, 48 mm external diameter and almost 800 mm long. Not sure about measure in inches :)

@@340dave6 I worked as a mechanic some 30 years ago and belive it or not this was a method some of the guys used although there was a press and tools there. An oxy/acetylene is of course more effective than propane torch but i wanted to do it in the most simple way i could.

Quote from the Chrysler factory service manual (1971): "CAUTION: Under no circumstances should axle shaft collars or bearings be removed using a torch. The use of a torch in the removal of axle shaft collars or bearings is an unsafe practice, because heat is fed into the axle shaft bearing journal and thereby weakens this area." To safely remove the collar(never re-use them) simply drill 2 or 3 holes across the outside face of it and then use a cold chisel to split the collar. The collar is what stops the axle from exiting the rear axle assembly with drum, tire and all in tow; always replace it. Your bearing should come with a new one.

Luckily this is a 1970 axle :) just joking. When we deal with old stuff that is stuck or rusted, which they never had to do when they wrote the service manual, we usually have to go beyond the manual. In general I agree with the manual but as long as we heat things and are careful to not overheat things, change color, turning blue or purple, affecting hardening or tempering we should be on the safe side. I have seen plenty of other metods like drilling or using an angle grinder leaving nasty damages in the axle wich are perhaps even worse. In this particular video I wanted to show how to remove the collar in one piece without having access to drill or angle grinder. The same with the bearing roller basket. The struggle removing the bearing that way makes it possible to use the bearing rings for other jobs in the press or whenever they could come handy :) I'm awere that there is a special tool for just about everything you can do on a car but In the video serie Ifixmycarmyself I always try to show how we can fix things without half a million $ wort of tools, just like the average garage guy situation and perhaps does'n even have a sevice manual. That is the basic principle for the wole channel. Thank you for your comment!

The amount of heat he is putting into the bearing race, with what appears to be a propane torch, will not harm the axle. The FSM is likely referring to oxy-acetylene, which does create enough heat to harm metallurgy.

Haha, don’t worry, these particular bearings are ball bearing and the bearing retainer slides over the bearing and a locking ring fits in a groove on the outer bearing ring and will keep the bearing and retainer in place. But if it was a conical bearing I would for sure share your concern :)

Cut a groove into the inner race, careful…not all the way through. Strike with hammer/chisel and the race splits , slides off.

@@Titan-dm2mo in the past I have used a cutting torch . Just enough to blast a groove without penetrating into the shaft. Sounds difficult but easier than you think. I have used cutting discs and carbide burrs. The race is so hard that all you need is a start and it will fracture very easily and slide off.
