[TR] Tow Bar Blues

[William C. Quincy]

Greetings Listers,
Several years ago I found a tow bar that matched the bumper hole  
pattern perfectly for my TR3. I've used it many times with  
inconsistent results when turning corners.
Some times the front wheels refuse to turn and scrub around the  
corner, other times the wheels turn all the way to lock, and refuse  
to straighten up causing me to get out in traffic and  straighten the  
wheels before I can continue down the road.
I like towing this  car on all fours in a straight line, but would  
like to hear from the list about why the bad behavior turning corners .
Thanks
