>> Hi TTers,
>> I got that Rohn 45 tilt-over down and home last week. In remarkably good 
>> condition. Only thing I wondering about is the TB3 thrust bearing and how 
>> to lubricate it. It turns freely but has a notable rumbling sound and 
>> feel to it. I notice at the bottom of the inside shaft area where to mast

>> place to remove and squirt in some white grease? And then replace the 
>> plug?
>> Thanks for your guidance,
