Really shouldnt be. Try to just line them up bye eyeballing it. Other then that did you lube the splines? helps a little. Also try to use a little um power. Hammer and a decent piece of wood has been know to help. Just make sure and put the wood between the hammer and the shaft. At least this is how I have done any with issues.
Problem solved I hope. Looks like the parts supplier gave me the wrong half shaft. (I got shafted) It appears the axle shaft is about 3/8 inches to long! Will be back at the parts store this morning. / J
If that's not what's going on, you literally have to grab the shaft by the end, pull it as if it's dislocating, and then JAM it in HARD. I literally pulled on and slammed mine back over my head against the tranny before it went in. Had about 1/8 inch of gold showing between trans/shaft, runs fine.
Went to parts house today and they don't have anything in stock. I had to put the original back in. Took less then an hour. It looks like this car (not mine) uses a half shaft for a vehicle with ABS. This car does not have ABS. We saw that from pictures on the web from parts houses. It has the pick up at the wheel and a cover for the seal at the trans axle. Now need to locate transaxel fill hole to replace fluid that leaked out when we pulled the shaft. / J
