I decided to finally fix my front diff today. THere was loads of up and down movement on the input bearing. 4 wheel drive was not really possible.

The pinion bearing is totally knackered. The pinion gear and the big ring are both missing quite a few teeth. Also these bits of metal were lying in the bottom of the diff casing:

I take it just putting a new pinion bearing in wouldn't be good enough? I'm thinking of just replacing the whole thing, they seem to go fairly cheap on ebay.

The diff end of my halfshafts have 10 splines but the wheel ends have 24, is that normal or has somebody mixed two types together?

Also the inner part of one of my wheel bearing is stuck on the stub axle... think I'll have to cut it off.

Kind of wish I'd just left it as it was!

Thanks
 
10 spline diff is all you need, the rest is normal

4.7 ratio unless its been changed for a later 3.54
 
As the doc say's just pick up another diff, to remove old bearing inner a cut some of the way through at an angle[to avoid the back of the stub] with grinder then a good whack with a cold chisel will split it.
 
Ok new diff it is. I would like to get a higher gear ratio so though of 3.54s but I would prefer the ashcroft high ratio transfer box, that can wait till I'm a bit richer though.

So with the halfshafts, are all 10 spline halfshafts 10 at one end and 24 at the other? I thought they would be 10 at both ends...

earlier ones were , but 10 or 24 spline only refers to inner splines ie diff end

Do the maths re high ratio transfer and 3.54 doffs square root of bugger all in it.

What about the 'math' of upping both low AND high range with the diff swap against just high with the ashcroft box ???

It's never bothered me personally

BUT if the O/P does lot of low speed crawling it might .
 
As far as I can tell it's a PITA to put 3.54 in a salisbury? Also I'd like to keep low box at the ratio it is.
