Re: A good buy or not
Looks like its off craigslist so someone mustve got it!
Anyway, these Jeeps a re pretty reliable all in all. Of course like anything totally depends on previous ownership, how they took care of, things like that. Without a carfax and history of maintenance/accidents, stuff like that its hard to tell, even with a mechanic looking it over once. All in all, the trannys are strong and as long as shes under 60k miles its good, anything over Id have fluid/filter swapped and the same with all the diffs.
And hopefully the oil was changed very 3k with something decent, if thats the case I wouldn't worry about anything there. All in all the suspension is the weakest link but with some upgraded endlinks and sways it'll stiffen up nicely. Also want to check out the shocks/springs, a nice set of coilovers would do the trick there!
As for vibration, could be a lot of things, wheel bearing would be my first guess, but if it was in an accident could also be steering related or something like that. GL to you in your quest, keep look on cars.com, theres a lot on there!
