broken rear axle

PostPost by: "trdr_gonzo" » Mon Apr 25, 2005 9:33 pm

Hi all,

Was out for drive sunday afternoon, and the faint thumping noise that
i noticed occasionally on deceleration got much louder. Pulled into a
gas station and discovered that the ujoint on the after market CV
rear axle had separated from one of its 4 connections, leading the
axle to get loose. This was the left side rear axle - the one
transferring all the forward motion to the car. I tried to limp home
with it, but lo and behold- hit a bump and the axle separated in
two. Rolled to a stop and had her towed home.

My ques is, Is this a common failure for elans? I plan to have a new
U-joint press fitted onto the drive shaft - shall I have the right
axle u-joint replaced as well? Does the left side naturally recieve
more stress because it drive the car at speeds and hold it in place
when the car is parked (left in gear)? How difficult is it to
remove? Seems like all i need to do is unscrew the allen bolts and
take it to a mechanic to get the new U-joint fitted. Thanks in
advance for the advice.

Is it a u joint or cv? Would think u joints would be a no no on an elan, too much deflection almost for cv even.



U joints would need limit straps or they may break

cvs shouldn't but if the shaft is not the right length it may beat the circlip off the end of the shaft

-Hi , The last message was empty. Sorry for the confusion. The setup
on my axle is with universal joints, not with CV joints. Its been
on the car for at least 20 years with no problems. I will post a
file photo of it (before it broke)

thanks

Frank

I have the modern TT sliding spline, UJ system. It is true that the UJ
bind at full droop, I just fitted TT rear shocks, these allow less droop...
I have also experienced a fair number of UJ's going on an old spitfire I
had. Best thing to do is to renew both sets (the UJ's are pretty cheap
and if they have done 20 years service thats pretty good). Its probably
worth checking the houseings to see if they have worn oval and circlip
grooves for wear
Cheers

Converted mine a couple of years ago,apart from one tired u/j that neededreplacing it has performed faultlessly,no more Kangarooing-especially in reverse.True to say though the joints are near to their limits on full droop
