general problems of the 2000 Jeep Cherokee

I bought this truck used from a private owner in March of 15, check engine light was on was told it was on because they changed the gas cap on it in June of 15 I was at a store parked went into the store came back out truck wouldn't start no lights nothing jumping didn't do anything had to tow it home, then tow it to the repair shop where they said it was the starter and we placed that ( $394. 93) truck ran fine for about 2 weeks same thing, going to tow it the repair shop again next week.

When driving my 2000 Jeep Cherokee sport at 45-50 miles an hour the Jeep violently shakes from the front end. I researched this online and come to find out its called a "death wobble" among many Jeep owners. This is a scary phenomena as driving at highway speeds the vehicle wobbles back and forth and violently shakes.
