More trailer tire/wheel issues

"Highway travel is dangerous."


Nick- we didn't worry so much about dangerous situations when we were hang gliding with JZ and Zoardog. What changed? Lightning strike or something? ;-P~~~~

I pulled the drum off the wheel that was hot enough to steam water Both ends of the sealed bearing fell out along with most of the ball bearings! I believe the bearing was in the process of failing from overheated brakes after an hour of down hill towing......hwy80 west of Reno. W&W didn’t have the replacement and Cobra is on Holiday, but I was able to find it on line for $45/ea after giving ID 30mm, OD 60mm, H 37mm ( old bearing was. Armed AL-KO 581736).
This is the second time I have had very hot brakes after an extended downhill tow. I have fitted a simple brake lock-out that prevents the surge brake from surging! It consists of a piece of plastic pipe who’s ID matches the OD of the surge cylinder (2� pipe X3.75� for my Cobra), split it into two halves with a hacksaw and place them on the surge brake in the fully extended position. Secure them with two hose clamps and I’m good to go down the Sierras without hot brakes! E-mail me for photo.

PS, my blown tire was most probably age related, these new looking tires all have a born on date of 99!

I just changed the tongue damper on a 10/2007 Cobra.
Had been in procrastination mode. Perhaps others put that job off too?
Thanks for keeping the thread going as a reminder!
It took 90 minutes from chocking and jacking the trailer prior to removal until rolling it out with the new part installed.
This part I believe is critical in maintaining good braking behaviour.

There is an Al-Ko Workshop manual, covering axles, brakes, hitches and overrun devices. It also has lists of lubricants and accessories.

The missing information for those with the square tongue:

Remove the jockey wheel.
After disconnecting the brake rod, remove the two bolts holding the drawbar onto the tongue.
Remove the drawbar.

Tools:
17mm open end for the brake rod. 19mm socket and open or box for the other bolts. Alignment tool for the new damper. Torque wrench.
Options:
Hammer, beer.
