what year jeep? the 87 uses the ford starter used on cj's. the 88 and up uses the style with the solenoid on the starter. the 87 is known for noisy starters, mainly because there are few starters that will work but only one correct one. mine has been noisy for years, 3 different starters, all noisy until the 4th one, finally people don't turn and look when I start it. I compared it to the old one and the end where the drives at is about 3/8" shorter on the quiet one. all I can tell you is keep trying different ones till you get lucky like I did.
