oh and i do see the point in you being reluctant to encourage back yard diff modding.

Some of the shit I have seen over the years is terrifying.

I'm not trying to be a negative nancy for the hell of it. A diff is a pretty important part on a car that needs to be right, much like brakes.

I see the big reason we have so many rules and regs these days with modifying cars, is that somewhere along the lines, accidents have been caused by poor ideas, skills, materials etc and recommendations have come out to tighten up the regulations.

Rather than sleeving and butt welding tubes together, look at cutting to length and welding new ends on instead.

The bearing housings for common diffs like 9" and borg warners are reasonably cheap but I don't know about suzuki ones.

For the fronts, the big ball on the end will more than likely have a shoulder already pressed into the tube. If you carefully cut out the welds you should be able to re use the end.

This would go a long way to satisfying any engineering requirements. If you duplicate what was originally there, it looks better on paper. If you put a join in then it is an additional failure point.

All the welding would need to be done as per the Australian Standard too.

Totally agree with everything but we are talking an LJ for off road use here (I think) not some abortion with a V8 motor for the saturday night Pitt street drags.

Nice attitude JB

Was just saying how things easily bend with weld.

You don't think that off road use is somehow easier on vehicles do you?

No but done at a much more sensible pace that does not tend to break people just cars.

in the jig above where they got alloy pucks made.

any one know if using bearings that fit the sizes needed would work instead?

I don't have access to do it, I can just grab the last couple posts as quotes though?

I'd call that a checking guage, not a jig.

Jig or not a Jig, seems to me a crap load of people narrowing diffs using this method.

Whatever works. I just think they'd be more at home in this thread.

X2.

Buds customs use the same system for their custom housings. They seem to be moving quite a few of those, so it must work.

There was a good write up in Street Machine sometime in the last year or so about the custom diffs that Difillipo does.

They all go in the press to straighten after welding.

A company I once worked for made a jig for a doorslammer team. They used it for their top fuel bike chassis and I remember seeing a diff being built on it at one stage. It was 25mm or 30 mm plate and once all the fixtures were in place you could completely mess up the sequence and it would still come out straight. These diffs were quite short end to end though.

the last page of this thread he swaps his centre to the other side. you could use the same idea i guess.

I will have a look for that issue when I get home tonight.

i found my copy, was the june edition... don't have a scanner at home but here are some pics of the jig.







even with a jig like that it still ends up having to be straightened.
