OK, I had the 68 out today and..

[72 K20 Fleetside 4x4]

I got a crazy vibration in the front end on the passenger side at about 40 mph. As soon as I hit the brake pedal it eased up and quit once I got under about 25. About 10 minutes later it did it again only slightly worse,since I was only about 5 miles from home I headed there. I am sure the front end parts are worn out but I don't have any knowledge of what parts I should look into ordering and replacing. I do have a "bible" to help with the repairs if anybody can point me in the right direction. Also I wanted to order some new shocks if anybody has any recommendations for reasonably priced stock replacements.

Thanks again for your help everybody! I really appreciate it. I was hoping to get some more miles on the old girl this year.
