Re: For Alex Lynch, answer to tranny output shaft (archive)

Thanks. I replaced the output shaft seal, transmission mounts, and centre support bearing about three years ago. That is when I noticed the play between the splines on the output shaft and the splines on the flange. When I re-installed the flange nut, I smeared the back face with a little Permatex and torqued the nut to the factory specification. I haven't had any leaks since then.

I don't have a leak now but since I am replacing the driveshaft I will replace the output seal and transmission mounts as well. This time I will use the high strength Loctite #271 on the splines to hopefully remove the lateral movement in the flange. I didn't simply replace the flange since I don't know if the wear is in the output shaft or the flange. I want to stop any lateral movement to avoid damage to the new driveshaft.

The clunk in my transmission occurs just as the car is coming to a stop when the transmission shifts out of top gear. I think the problem is a combination of worn driveshaft u-joints (226k miles), lateral movement in the output flange, and a sticky valve. Frequent transmission oil changes have improved but not eliminated the problem. Perhaps the Loctite and new driveshaft will cure the rest.

Thanks again.

For some reason, the e-mails aren't going thru:

Loctite #242 is the general purpose compound which should be removable if you want to separate the parts in the future. I put mine in dry because I hadn't learned of the Loctite trick yet, & exceeded the torque spec by another 30 or 40 ft-lb & used Loctite #271 which is the permanant type, on the flange nut threads only. I put permatex "Ultra Copper" oil resistant RTV on the back side of the flange nut & at the very ends of the spines & yoke because the splines are a leak path. So far mine has remained tight for 2 years. When I did the job, the flange nut wasn't even finger tight when I opened it up.

I narrowed down the clunk in mine to the CV joint at the rear of the driveshaft, about 3 or 4" ahead of the diff input yoke. Mine makes a subtle clunk as it transitions between accelerating & coasting & visa versa, but has stayed about the same for the last 20k miles. No vibration in the driveshaft because of it. It's available as a separate part so someday I'll see if Hendrix can get me
one. Rainman gave me the ETK part number. Let me know if you find yours is loose & I'll e-mail you the info.
