First time putting front hubs on - any tips

[tdskip]

Making steady progress on the TR4A. Time for the hubs to go back on, and I thought I'd ask if y'all have any tips on doing this.

Manual makes it pretty straight forward, but...

I think we discussed this before ... if you are installing new felt seals, you should do a trial fitting without the seal to set the bearing clearance. Then mark the nut location, remove the hub, install the seal and put the nut back where it was. Otherwise, the felt may interfere with setting the bearing clearance.

I also rather like Geo's tip of JB Welding a 10-32 nut inside the dust cap, to which I then add a short 10-32 screw to block the hole in the cap. The nut makes it much easier to remove the cap in the future (remove the short screw and insert a longer one, which will force the cap off).

Also worth noting perhaps that the new rotors I got from a supplier in the UK (on sale at a show) were significantly off balance. I removed enough metal from one so the assembled hub wouldn't turn under it's own imbalance, but didn't take the other far enough it seems, and there is noticeable vibration at higher speeds. So I'm going to have to revisit the subject soon.

Hi Randall, yes, a bit of an echo. Sorry.

I just did this on the 3A project, and other than making sure I greased up the bearings thoroughly it went pretty smoothly - with the thinner grease seals I don't think you'll have a problem at all.

The only finicky thing I had was one side where the inner bearing didn't want to go on the axle stub. I cleaned up the stub with a little emory cloth and it went together.

So how to you guys like to measure float?

Good tip BTW on the 10-32 nut.

Tighten until the bearings just start to bind (hub doesn't spin as freely as before), then back off 1/2 flat plus whatever it takes to get the cotter pin to line up.

Well that makes it easy - thanks Randall. My manual didn't offer that as an option.

You should probably get one then.
