well i read somewhere that 1993 jeep grand Cherokees with the 2.5l had a terrible engine problem where it would vibrate from either the engine mounts not installed properly or another factor. this is the only year with this problem. if it doesn't have a 2.5l, idk what ur problem is. P.S. they stopped putting the 2.5l engines in the 1993s when this problem arose. buy another year or engine. If it is shaking while driving, and you feel it in the steering wheel, check balance on the wheels, then replace the steering stabilizer, if it is going out you will be driving along just fine and then it will start to shake like crazy and wont stop till you use the brakes.
In 1993, the US Mint produced a American Eagle Silver Bullion proof coin with a mint mark of "P." The 1993 coins that carry a mint mark of "S" and "W" were in a mint state of MS65. Mint State (MS) is a value used to grade the condition of the coin. This range runs from MS60 (not a good quality collector coin) to MS70 (a near perfect UN-CIRCULATED coin) sold directly by the U.S. Mint. The "S" and "W" mint marks indicate that the coin was minted at either San Francisco (S mint mark) or West-point (W mint mark). Even though these coins were specially minted and handled they may have a grade less than MS65 and, in rare cases grade higher than MS65
