: longfield install problem! re: hub and splines

ok here's the situation

both hubs will fit on one of the super axles.

but neither will fit on the other. even though both super axles are exactly the same! we don't want to try filing the axle splines down - don't want to screw up the splines if i've just been sent a defective unit or something.

has anyone had a similar problem? i've done a search and the only install issues that everyone here seems to run into are involving clips and fitment of the outer bell of the superaxle into the knuckle.

any advice is appreciated, we were hoping just to tear down and rebuild the axle in a few hours (needed to add wheel spacers and new bearings and a knuckle rebuild kit) and this is a major pain..:confused:

Look at the end of the birfield. It should be obvious if the if the hub won't go on at all. Usually it is because it has been dropped or someone has tapped on it and the splined area outside the snap ring groove is a little buggered up. I'd file it a little. I'm sure Bobby will send you another one for no charge but you'll have to wait for it.

argh.

i was worried that this was the problem.

yes, the birf was tapped firmly on the garage floor to insert the inner shaft.

i explained to my friend that the reason we shouldn't have done this was because of the heat-treatment on the birf makes the metal less hard than stock, ie. more prone to warpage?

anyways, hopefully it'll be back together tonight.

thanks for the advice - please put that on bobby's webpage or on the toyota faq, anywhere so no one else makes a similar mistake and wastes a lot of time.

I deformed (by dropping :eek:...) 3 splines on my rear axle shaft last night while we were rebuilding the rear axle. Wouldn't slide into the detroit in the 3rd member. :mad:

I didn't have a file narrow enough (V-notch) to notch the edges of the splines, so I ended up using a hacksaw blade. I'd cut a little, test fit, and repeat. I wouldn't want to cut new splines into an axle shaft this way, but since I was only working with the first 1/16th of an inch out of about 3 inches of spline surface, I don't think it will hurt anything.

why are you dropping it to insert the axle?
it should just slide in, unless you ar putting that inner clip on.
which is a no no with the longfield.

what did you drop it on/off etc. how hard? the longfields only got a couple of whacks for this to happen it seems.

Bobby doesnt do any heat treating to the end of the axle where the hub goes on.(making it softer) Boogered up splines on the end are pretty common. just file the end or do whatever you have to do. I can tell you that bobby slips a hub on the end of every birfield before he ships them out,just to make sure the splines are ok,and many of them need to be filed because somebody has dropped them or whatever.

Uh oh i would remove that inner shaft now to get the clip off if that is what you did. because you will break a inner shaft before you break the birf.

No inner clips on Longs, if you break an inner shaft you'll never get out the little chunk of shaft.

You can marlin tack the inner shafts if you want to keep them from sliding into the diff to far. I think marlin has pics of this technique on his web page. www.marlincrawler.com

a little surgical filing works every time.

Ypu. And like I said above. If you can't find the right size, use a hacksaw blade. Go nice and slow and it works every time. :D
