Will 1988 MFI GL cv axles fit my 1986 carb GL?

[Kwiknez]

Hello,

I was scrounging around at local junkyard and found a 88 GL that was pretty decent, grabbed a few parts of course, I saw that someone had taken out the transmission and left the cv axles on the backseat floor. Being that my cv's need new inner and out boots I was considering picking these up and just rebooting them and installing, my quandary is I read that the cv in mfi is different than carb. Spline is the same but the distance between boots is different. Does that matter?

They should fit fine.  The only different CV axle was for the turbo car.  But count the number of splines on the inner cup, I believe there should be 23. If you have 25, it won't work.

Apparently some later model MPFI cars had 25 spline front shafts also like the turbo cars. There's also difference thickness shafts depending on transmission type.

As Cyfun said, count the number of splines first.

 

But if your CVs aren't clicking or anything, I wouldn't bother changing them. Just disassemble the inner one, remove the boots & repack both inner & outer with grease & put new boots on & reuse your existing inner. Outer ones tend to go before inners because of the steering.

Thanks for response. I know that 23 spline is needed. I just need to know if the shorter distance between boots on the mfi compared to carb would be a problem.
