Snap!

I've only been waiting for a few weeks though.

Just ordered a couple of 25X62X8 oil seals. Hopefully they will solve it, because it pissing out the other side as well now :lol:

Think Scotties bearing seals were keeping the oil in so his bearings are lubed with diff oil. Seems to work.

How are you planning on getting to stock width - cutting down a sammy axle, or using a 413 axle with 19mm spacers each side?

I'm thinking about making a jig for the axle to bolt to that is squared, then cutting the axle down and welding it back up with trusses. The other option is to make an adapter to space out the end of each axle by 19mm - I thought about making a stack of plates - 3 lots of 5mm and a 4mm steel plate. Once they're in place I'd just tack weld them together to keep them steady.

I've been thinking about the adapter route and I worry that the bolts would have to be a bit long, and therefore might be under excessive stress.

What're your plans for getting it to stock width, mate?

Rich is doing the lot. Front and rear cases. Trusses, gussets, diff caps, YJ spring mounts, shortening a samurai rear axle and putting new flanges on the ends to take a front hub and disc carrier and making shafts to appropriate length.

Be like brand new when i get them back, fully armoured and bolt straight on.

There is a huge amount of force exerted on the adaptor, need to be billit I would say.

When it comes to axle trussing and cutting and welding axle casings I've done some bad things !!

Making a jig won't help I did that and when I welded it it still bent, it's more about the way it's welded.

I think my back axle now isn't conplelty stright it's so easy to get them to hot whilst welding them

Yes, I don't want to bend the axle - I'm going to try to get "special" Ross from HPOC to help me out with the welding, he's one of the top coded welders in the country.

I'm going to make the trusses etc, then either drive down to him, or wait until he pops up to London next.

It's not a big issue for me to wait, I have a feeling that Rockwatt is super busy right now, and he's going to have me waiting a while for my kit.

Fresh new hub seals keep the oil in, mine has only leaked once and I just throw in a new hub seal.

It's not an ideal design without the shaft oil seal but tbh i've had minimal issues and the constant feed of diff oil has helped prolong the rear bearing life.
