1987 GL 4wd station wagon.

 

I just finished installing new front axles. When i let the clutch out, the car goes about 3 feet and the roll pin that holds the axle to the half shaft breaks, on the drivers side. The passenger side seems to work fine.

 

There seems to be some extra play between the axle and the half shaft, like the socket part of the new axle is too big, or the splines are not right,

I can install the new axle and pin, and rotate it by hand, but it seems looser than the passenger side one. The passenger side one fits nice and tight, but I can rock the other one with my hand.

I have taken it back to the parts store and we measured the inner diameter of the two axles and they were the same. The two axles have the same part number, and are supposed to be the same part.

 

I am guessing that the splined part is wrong, probably the wrong piece installed at the factory.

The power from the engine is being absorbed by the roll pin and not the splines like it is supposed to.

 

Am I right, do I have a defective or wrong part, or is it some else?

 

Any input will appreciated.

Thanks in advance.

sounds like you have a Turbo axle on a N/A car. Turbo axles are 25 spline, regular ones are 23 spline. Count the splines and see what you have.
