I've been converting my project car from 4 to five lug and have run into a snag. After installing new bearings in the rear, I attempted to draw the rear hubs into the bearing using the tool below. No matter how careful I am, the hub starts to go in crooked so I stop, not wanting to force it it.

So what's the trick to getting these puppies started straight? It seemed like an easy enough task.

I do have the rear arms mounted, thinking it would be better held in place. Would pulling the arms and having the laying flat be any better.
Thanks

Hey Mark,

You have the right idea on the tool. Is that socket large enough to rest on the bearing on the back side while you draw the hub in? Seems to me when I did this the socket was bigger.

Also the hub will try to tilt initially as it tries t start. I snugged it down and tapped on it with a dead blow on the "high" side while turning the wrench. Started going in straight then it is easy.

The job is no easier with the arm out of the car either. Patience will pay off, maybe a helper to get it started.

Hi Jim...actually my setup uses all thread and uses a 2 inch socket that rests on the inner bearing race. I was afraid to force it in...destroying the bearing. Maybe another day with a fresh start.

Thanks for the tips!

Spin it. Find the high side.

Lightly Tap-tap with a rubber mallet to even it out.

Tighten the nut again.

Repeat.

After you get it started it begins to pull right in.

You'll know when it's on the way.

I freeze the hubs and warm up the inner races to about 90-100 degrees and I use anti-seize on the parts that I want to slide. The last 2 sets that I did I was able to push them in by hand almost all the way.

+1 on freezing the axle shaft. A night in the freezer does wonders for the interferance fit of the two parts.

Well, the hubs are in the freezer next to the pot pies (IMG:style_emoticons/default/av-943.gif) . I think I'll try to heat the inner races as well...if I can just get then started straight, I'm sure the rest will follow more easily.

Thanks!

What kind of Pot Pies? It's very important not to put the hubs too close to any chicken pot pies. Beef and turkey are fine.

Why would you freeze the axle shaft? It's a slip fit into the hub ...........

Looks like the hubs have been plated, is the bearing surface clean on the hub?(down to the original surface)

The added thickness of plating will cause a problem.

Just a thought

That's a good point. The machined surfaces if plated will cause problems. It is hard to tell in the photo if the part circled is plated. If it is, it will need to be machined off.

This picture is not my hub--just used because it is the same setup that I have...I have a clean mating surface on my hubs, no paint or plating.

Now, if I can get them out of the freezer and to the garage without my wife spotting me. At least they're not greasy...

When I did mine, the side I heated with the map gas went in easier. Froze the bearing first too.

If your wife grows accustomed to hubs in the freezer and maybe grease rags in the washing machine it will make it easier when she comes home early to bust you with an engine case in the dishwasher.

The pot pies, I mean the freezer, did the trick! Hubs pulled right in...yeah! Also unscrewed the ends out of the steering rack...ready for the turbo kit.
