I have an i30 vlsd auto tranny and was wondering about some specifics of the following. If one axle was taken out if the vlsd would then put all the power to the axle with resistance? If so will this prematurely wear the diff out? If so will welding it solve that problem of premature wear? And if it does require welding to save on wear would locking up the diff then rob me of availible power seeing how it would now be designated to spin both axles? Or by have no resistance on one axle does it make it all negligable?


BTW, does anyone know what the spline count is on the input shaft of a 240 auto tranny?

 

same as the 5 sp, same as the Sr, same as the VGs, same as most. 24 im pretty sure

 

Thanks, as always your so much help.

Edit.....do you have any idea where i may locate the complete conv. top assembly of a 300z?

 

if you take an axle off the vlsd, then with tires on the ground, it will spin the opn end. the stock VLSD's are weak. and yes, it will ruin it. and no, you cant really weld it withouth taking the diff apart because its a housed diff unlike an open. wlding diffs doesnt necessarily rob hp, but makes the car a bit harder to drive. they like to understeer alot if youre not sliding it (i.e. normal driving)

 

Interesting...keeep in mind we are talking about a diff in a FWD......
For some reason i thought the vlsd would turn the axle that had the most traction. That's why i was concerned about a premature failure due to a constant lopsided equation.
So would it be easier/better/more logical to replace the vlsd unit with an open unit that has been welded? Or are all the diff. (more specifically the ones in the i30 and maxima) housed the same way, thus making it difficult or labor intensive to weld even the open diffs?

I know you have seen plenty of trannies in your time. Do you recall the spline count on the input shaft of a 240 auto tranny? Just looking for conformation of the above post. And is the input shaft the same on an auto as it is a manual for the 240? Do you know if all VG, VQ, RB, KA motor series mate up to the 24 spline?

 

i would assume that welding the differential on a fwd would probably be the most terrible thing you could do.

 

way to much stress up front

 

Guys, you all are reading way to much into this. Can't go into the extreme specifics of the project for various reasons, but try not to assume to much. I never said i was trying to weld a diff so i can run peg leg around town, nor can i mention what this will be attached to. I can tell you that one axles will be required to move around 2000-2500 lbs in stop and go situations. Mainly i'm just concerned right now about seeing if it would be feasible to get this thing going. Reliablity would just be a pleasent afterthought.


Thanks for the replies so far though.

 

fwd motor in two a 240?
