This weekend I nearly emptied a 500 ml bottle of the Penrite Steering Box Lube into my '59. Thirsty bugger, but I must say the improvement on today's drive was noticeable.
I used the Ziploc baggie method to fill the box, after squeezing in as much as would flow, and having the front wheels jacked up, I'd turn the steering wheel full lock 2-3 times. This would draw the Penrite down into everything. Repeat this a dozen or so times and it filled up nicely. I left a 1/4" or so air space.
The big thing I noticed being improved upon was how the steering felt when going over sharp bumps, like an expansion ripple. Before I'd often get a metallic clank sound thru the steering wheel. Tonight hitting that sort of pavement, things were just a nice thud/thump. Impressive, I should have done it long ago. Best $28.50 spent so far.
