I have a 2002 ZX3 that needs the front axles to be replaced. The ones my mechanic sourced were an inch and a half too long. He went to his second supplier and got the same dimension axles. To his credit even though he fussed with the car for two days he would not take a cent for his time.

Is there a trick to finding and buying axles for the 2002 Focus ZX3 (manual tranny)? Are there different transmissions on these models that have different length axles? Who would you go to (other than Ford) for the axles I need?

Thanks in advance for any advice you may offer.

I suspect the mech, you have to research for the correct axle and not that hard. Never had a problem. The axles may be the same or not, often one is and the other is not.

Don't be too sure you need both either, I commonly never change but one and the other still stays running fine.

Rock Auto for parts and they describe them but of course you have to read. Much cheaper too, I use A1 Cardone Select when available and excellent part at a price so cheap you have trouble figuring out how they make any money there.

From what I've dug out, here is what I believe:
There are two manual transmissions it could be, the IB5 or the MTX75.
The IB5 does not have a drain plug, so mine must be the MTX75 as it has a drain.
The MTC75 has 25 splines on the outboard end. The IB5 has 23.
I will be able to check this out in the morning.

Based on amc49's recomendation to check out Rock Auto, I believe that their part number 602144 may be what I need.

I'll let you know how things resolve.

Thanks, amc49 for the advice.

I tried to remove the axle using a slide hammer. The hook end broke off. I ended up McGuyvering things by looping one end some heavy airplane cable around the axle behind the inner joint and and the other end around the business end of a 10 pound sledge. One golf swing later and the axle was out.

I verified the spline count as 26, which confirms that it is an MTX75 tranny. AutoZone had one in stock and after verifying dimensions at both ends and end to end length, the installation seemed to go well. Except for the fact that the inboard end did not click into place. After several tries, I backed off to avoid buggering up the seal.

Is there a trick you have used to get the axle to snap into the tranny? Is it acceptable to put the old nut on loosly and give it a good whack?

Any advise is appreciated.

Greasemanicure,
I replaced both drive axles in my 2002 5-speed/Zetec SE wagon summer 2018. The 'trick' to easily removing the drivers (left) side axle is to remove the passenger (right) side first then use a thin long screwdriver, etc, to drive the drivers side axle out from the passenger side of the differential. On mine it just took one good tap. Very simple, no drama. This was suggested by other FFF members.

The axles I purchased:
NAPA 94-7030 (left)
NAPA 94-7031 (right)

During re-installation I did need to gently tap on the outer end of the drivers side axle to get the inner snap ring to seat in the transmission.

BTW my understanding of the CV axle usage is as follows:
Zetec (DOHC) and SPI (SOHC) used the same Automatic trans (AT)
Zetec used MTX75 manual trans
SPI used IB5 manual trans
Auto trans (either engine) and MTX75 (Zetec) used one set of CV axles
IB5 (SPI) used a different set of axles

Good luck
Paul

I tend to grab the long axle center shaft and by hand impact the inner stub shaft to pop it past the clip. I check by feel first, if you impact too hard you can ruin the inner boot or the internal tripod. I also stick the stub axle in without a clip on it at first to see if there is any slight damage on the splines themselves that stops the axle from freely going in, it should go in fairly easy without the clip on it as a test.

Post fix wrap-up:
I took the old inner joint, removed the clip and used it to check the installation process, feeling my way along. I then tried with the new axle and the splines seemed to engage the transmission. I aligned the axle as best I could with the old nut on the axle, and the second tap with a mallet had the axle snap into the tranny. It helped to loosen the three nuts at the top of the strut to let it be moved out of the way.

Thanks to all for the help and advise. I'm next going to tackle the valve cover gasket when I have another warm day.
