no power to the ground??

I finally got around to replacing my axles on my 90 MTX. The Haynes manual says to not replace both axles at once, so I pulled the right axle and the link shaft. The axle separated from the link shaft easily and it all went back in. The left side also went in easily. Dropped the car off the jack stands and went for a ride. About 2 miles from the house at a steady cruise speed, it was like the axle shafts disconnected. No bang, no noise, just all forward gears, but no movement. The book stated that is you were pulling both axles at once, then you must insert a wooden dowel in place of the axle to keep differential side gears supported. Otherwise they fall in the case and you are in deep doo doo. I got it home and parked it without looking underneath. Are the axles perhaps not seated fully. Any clues???

About the only way to tell is to look underneath.

well... as not doing both at the same time...good idea...but (someone correct me if i'm wrong) the shaft that comes out of the transaxle on the passenger side of our cars holds it all in place (transaxle inner parts ) so that shouldn't be the problem.... when you were putting the shafts in..... did you pull on them at all or possibly separated the shaft at the cv joint?...

even though you aren't moving....while you have in drive....does the speedo still go up in mph???
if so it's some thing with the out put shaft ithink.....

You can remove both axles at the same time in the MTX-IV. The axles don't support any diff parts.

Gotta make sure the c-clips in the end of the shafts lock in place.

A check underneath revealed the problem. The Driver side (left) axle comes directly out of the transaxle. The Right side comes out to a link shaft and then to the axle. When I pushed and pulled on the link shaft, it moved in and out of the transaxle. I pushed it back in as best I could. The car then moved under it's own power, but not for long. The Hayes manual has a procedure for pushing the link shaft back into the transaxle with a reverse puller arrangement. I did not notice, but there appears to be internal circlip on the link shaft that will lock into the transaxle. When I pulled the right side out the first time, the link shaft and the axle came out as one. Does the rubber pillow block arrangement do any holding on the link shaft?? I'll keep everyone posted.

If I remember correctly from when I did this in December for the passenger side:

There is no circlip on the differential end. There is a circlip that locates the outer half-shaft into the link shaft support bearing. The bearing housing is bolted to the subframe with two bolts. If yours is *not* bolted in place then this would be the cause of your problems I would expect.

Search 'shaft' here at the forum to get yourself caught up regarding the right side drive shaft, my friend. If the bearing (which is press-fit on the shaft is sliding out of the rubber pillow block, well, that means there isn't anything holding the shaft in the diff. There is no circlip on the right side shaft. The bearing holds the shaft in the diff.

Let us know if that's the case.
