Has anyone had this problem or can anyone confirm that 'jeep' starter motor only is suitable and why?
Aftermarket parts are aftermarket which in turn are not exactly OEM, granted. However you will sometimes more than not get a fairly decent part from your local parts store. I have to say that unless, the retail aftermarket starter's gear was not aligned properly or gear housing damaged, issues can arise. To answer your question. However, I have to say, the same issue has arisen before in a Jeep Liberty 2.5L LTD, closes thing I have over here. When this happened to me at work, I just ordered a factory starter and ate the difference to help the customer out. Rather this is helpful or not, I gave it a shot. Unfortunately, I do not have anymore information, but will research some more and get back.
