G50-01 CV flange spacer?

[2001ultima]

Question, Does anyone have an idea why there is a spacer between the CV and tranx flange? See Photo at link below. Any guess?

Not seen that before.
Perhaps the shafts are not standard length.

Could they be of an older generation shaft?

[F.C.]

Shaft length/gearbox flange to flange width on that model box or modded uprights.
Either way it looks sound enough from the picture.

The original owner doesn't remember why the spacer was used as the car was built in 2006/7. From what he remembers the axles/CVs were originally provided by Ultima. Renegade in the US upgraded the transaxle. The uprights are OEM/stock. I looked through the build notes and saw that the car was worked by a third party racing shop to do a bunch of work and saw a receipt item "machine CV spacer" but no reason why. For some reason they thought the spacer would be needed. The only thing I can think is the G50-01 is narrow then a G50-52 or other. I'll see if I can measure the distance between the inner CV stub shaft.

that car has different wheels and different wishbones to the factory standard ultima fare. i would assume that the offset on the wheels has changed and the whole suspension has been lengthened to move the wheel back to the correct location. As a result the upright has moved further out resulting in the original axle being to short, to fix this problem a spacer has been machined to lengthen the sub flange at the gear box end and allow the whole lot to be connected again once the longer wishbones were installed.

Edited to add,
I have never seen this car, so don’t take the above as absolute truth, only an observation from previous photos that I have seen of the car. I believe that all the suspension pivots on the lower wishbones are either rod ends and that there was also a spherical ball joint mounted at the lower front portion of the wishbone. This necessitated a large circular housing that the ball sat in. can’t remember if it was staked/swaged in place or held in with “cir-clips” or “spiralocks”. I don’t know if the pick up points were changed and what if any affect has resulted in the location of the roll centre. If the wishbones have gotten longer with no other change then there may be a reduction in camber gain as the car rolls.

What I can remember is that from looking at the photos I very much liked the spec and the attention to detail that had gone into the construction of the car and that the changes that had been made looked to have been high quality, the above observations shouldn’t be taken as a negative observation, merely an observation of how the car is different to standard ultima offerings.

I like it.

ezakimak, I think you are right, the control arms were modified to convert from bushings to heim joints ends. The result must have extended the uprights. I have a friend with an Ultima. Next time I visit. I'll measure from the chassis to the upright and compare. Thanks.
