What Are You Doing To/With Your Car Today?

Replaced power steering line.
Replaced oil pressure gauge line (braided).

But the best thing I did was loosen the bolts a little on my leaf spring shackles.
My bouncy ride now rides smooth and wonderful!
I (stupidly) had them very tight not realizing the shackles needed to articulate. ....a couple cranks of the wrench and it's a night and day difference!
