remove all the stock rockers and replace them with the new roller rockers and poly locks at one time. by now all the rockers should be at or very near zero lash and you can crank the engine and begin adjustment without the rockers clacking. with the engine running. start with a rocker and loosen it until it starts clacking. Tighten it down until the noise goes away (this is zero lash) and adjust accordingly to 1/4 or 1/2 turn, whatever, past zero.

No. Since a chiropractic adjustment is a specific force, applied in a specific direction to a specific joint, it is virtually impossible to adjust oneself correctly and accurately. It is possible to turn or bend or twist in certain ways to create a "popping" sound that sometimes accompanies a chiropractic adjustment. Unfortunately, this type of joint manipulation is usually counterproductive, often making an already unstable spine even more unstable, and can sometimes be dangerous. See similar questions...

It depends on the product. Some O.E.M. hubcaps seem to be designed to fail. Clips on many minivan hubcaps are extremely weak and tend to break after the hubcap has been removed a few times. Good brands of aftermarket hubcaps are designed with stronger clips and will stay on longer than original equipment. The BIG difference: You can buy a whole set of aftermarket wheel covers for less than the cost of a single OEM cover. See similar questions...
