offset

Isn't the pinon offset quite a bit? It would make quite the asymetrical chassis.

I don't understand the post. Do you mean the diff, crownwheel and pinion?

The offset you describe is actually a bonus - the bearings in a propshaft will wear out very quickly if they are run totally straight (it's called 'brinneling' ) but work properly if driven at around 3 degrees.

If the engine and axle flange are parallel, but slightly offset then each bearing of the propshaft run at a slight angle, which is ideal.

What does happen is that the driver's side of the cockpit is slightly narrower, but it's not significant.

i've heard it said many times that the UJs wear out faster if totally straight. Can anyone explain why this is?! i dont get it, but than again, there are a couple of things i dont get...

If the UJ is striaght, the needle rollers stay in one position and spot wear the casement. If there is an offset, the rollers revolve in the casement and there is little or no wear

Hi All:

While attempting to respond to a post by SGraber, I mistakenly created a new thread!

Many apologies.

Aha! I kinda thought that's what happened because it fit the subject, but I haven't seen the offset of the rear differential of one of these little 4x4 trucks so I can't really comment. I will do a little research tho.

Yes it is...

Now that offset WOULD be a problem! I thought you were talking about the 2 or 3 inch offset found on an ordinary saloon rear axle.

The one you show would be fine for a one-and-a-half seater though...
