Like the title says, I can't get my driveshaft pushed into the rear of my transmission. I have consulted the tsrm., and in any case that the driveshaft is referenced, the manual simply says remove or install, and no further instructions are given. My searches on here also failed to turn up much of anything valuable for my problem. I have dropped the exhaust, so it is out of the way, and loosened and dropped the center carrier bearing. The bolts holding the two sections of the shaft together are frozen or extremely torqued, and I cannot break them loose. (I hit them with a heavy dose of rust penetrant.) I have lubed the splines on both the output shaft of the transmission and the yoke of the shaft, as well as the outside surface of the spline housing. I tried jacking under the center bearing after pushing the shaft into position on the splines. The thought was that as I raised the center of the shaft, the splines would push into the transmission as the shaft tried to straighten itself. It did not work. I can get about a half inch of engagement on the splines when I push the shaft up to the transmission, and it appears to be pushing on straight and not binding for that reason. But it is still binding somewhere. Has anyone else run into this before? Is there something that I am missing? The car is a '91 7M turbo-powered automatic with stock trans. and driveshaft. Thanks in advance! Can post pics if necessary. Also, the trans. IS mouted on the crossmember.
