My son has a 1991 Jeep Cherokee Laredo, 4-door, 2WD, with an automatic transmission on a 4 liter engine. Things are amiss in the steering column and he’s looking for a bearing for it. The problem is that Jeep was kind of using parts on an as-available basis for screwing these cars together and he can’t figure out where the steering column came from. He thinks it’s a GM part, but that doesn’t narrow it down much. Can anyone tell me anything about what it might be or how to find out what it is?
