Thread: Stage1 front diffs

The standard SIII 109 F/W hubs will fit onto a stage 1 front end, same 24 spline drive flanges etc. (Did he do that on an LT95 g/box?)

My understanding is that the only way you can tell the difference is to take the swivel apart and have a look for a spicer or CV halfshaft.

I agree with Diana - I think that externally they are almost identical. You can find the diff ratio by counting turns - assuming off the vehicle, lock one hub (e.g. adjust brake to hard on) and count the number of turns of the pinion for one turn of the other hub - double the number to get the ratio. Distinguishing between 4.7 and 3.54 would not require great accuracy.

Thanks Diana.
YEP,LT95,cant understand why.It appears nothing has actually been removed(ie all suspension bolts look Series old).When we but it on the trailer we had to back it up in gear on the startermotor as its a non goer,it wouldnt move,locked the hubs and away she went.
How about the 2 superchargers complete with MADMAX style gearshifter switch.The superchargers were a pair of demister fans feeding the aircleaner,I KID YOU NOT.
He liked air horns too,two sets,arieals and some other "interesting" stuff.

John you are correct about identifying the diff ratio, but it won't help with the CV joints.

If you look at tardis' SIIB camper, I am convinced that it is running a Range Rover front end with a Series 4.7:1 Series diff. so a CV joint and 4.7 ratio, the same as my red SIIB has Stage 1 swivels and CVs and the ENV 4.7:1 diff.

I can not see any other way to confirm the presence of CVs on a non goer than to crack open one swivel and take a look.

How about this - proceed as for diff ratio measurement, but turn on full lock.

If there is a wheel and tyre fitted, mark with chalk on the tyre each quarter turn of the pinion. For the CV joint, all marks will be the same spacing, for a cross and bearing joint there will be a measurable difference in the space between the marks, as the wheel speeds up and slows down twice per turn of the wheel

John

It could work, but I would want to do the same thing on a couple of known vehicles to compare the difference between the CV joints and spicer joints.

Would I be correct in thinking that with free wheeling hubs and an LT95 that you would have to engage the centre diff lock to move if the hubs were disengaged?

YEP,mentioned that in the second post.
