Scissor Jack replacement
 

I have a 1709T and would like to replace two scissor jacks. How do I find what size is the exact replacement? The reason for replacement is that when cranked up they will lower themselves. If you know a fix, I would try that before replacement.

Hi Ed,
When you crank the jacks into the upper most position do you add additional torque? It sounds like your jacks are well lubricated. Do they wabble when they are moving down towards the round? I took one apart and found it wabbled and was much easier to spin that the others even if they are all greased at the same time.
