I have a 98 Max AT,w/abs and just swapped a used 95 rt axle shaft mt, w/ abs in but it doesn't engage. I compared both, they looked the same and parts books show that they interchange. Is the inner portion of shaft a slightly different length and does it separate at the bearing plate mount?

 

Passenger side axles are all the same iirc. Why did you replace it in the first place? The inner joint may have separated inside the boot.

As stated remove the axle and check if the inner and outer shaft separated in the joint. When I was removing the right axle earlier this year the outer shaft slipped from the inner shaft because I didn't support the LCA enough.

All 4th GENs sold in the US have the same right axles. They are made for non LSD trans.

 

Is it an OEM shaft or aftermarket new or rebuilt?

 

Just learned some great news, my parts car is Canadian eh! I think its time for a swap.

 

You might of inserted an axle from a LSD MT. The input shafts are 1" longer for LSD. Take it out and compare the input shaft length on both axles. They both have 29 splines.
