big diff driveshaft measurements please?

[Jos]

I bought a pair of big diff driveshafts from a member here, but compared to my small diff auto they measure up the same.

According the manual there should be a 5 mm difference in the lh (shortest) driveshaft, wich I don't have/see.

I also measured them compressed together with a clamp, still no difference

 

So if anyone has som bigg diff drivehafts lying around and the time to measure them uncompressed and compressed for me please?, so I can see if mine are wrong or the one I received

 

The way I measured them:

 

uncompressed:

 

 

compressed

 

 

and what/where I measured:

 

 

 

My measurements of the lh (short) shaft were 550 mm (21.7 inch) uncompressed and 520 mm (20.5 inch) compressed

of the rh long shaft 590 mm (23.2 inch) uncompressed and 565 mm (22.2 inch) compressed

I make the short one 545mm uncompressed and the long one 585mm uncompressed. When I say "uncompressed" I mean - just as it is lying on the bench - I didn't try to stretch it any longer than it is just lying there.

 

Is that of any use?

Yes it is, thank you:thumbs:, it confirms my thoughts a bit, although it would be nice if more people could post their measurements

Jos fwiw, i took a couple of pics before i sent out my b03b package, regarding length of the driveshafts, it's pretty difficult to measure with the photocamera in one hand and hold the centimeter and driveshaft with the other so hope this is good enough to show the difference, I can off course when my driveshafts are finished get them measured again with the help of Marcel from MRS.

Mario, thanks for the effort, I must admid I had slightly forgotten this thread .

 

I do notice from your pic's and measurements I took from 2 other sets of driveshafts (both also from manuals with big diffs) that there's quite a lot of difference in the uncompressed condition.

However, after buying 2 sets from big diffs and comparing them to my own small diff shafts in a fully compressed state I found out there actually is no difference, so there should be no problem in fitting small diff shafts in big diff setups. (As some members mentioned)

 

Btw, good progress on your supra , in for pic's when the diff and shaft's are fitted.

^^Cheers Jos, yes will upload some pics of the installataion when time comes. You're quite busy yourself too, keep up the good work mate.
