Jeep Problems

[Stig]

Ok, I know that there are many of you out there that are either Jeep enthusiats, off road entusiasts or both so I have a question that I am hoping someone might be able to answer or at the very least help explain.

Last year I snapped the screw end of a bushing off in the trac bar. I replaced the trac bar and bushing because I was not able to get the remainder of the screw out. The replacement bar and buching that went in were the same ones that came out and are the heaviest duty trac bar and bushing that this particular manufacturer makes.

Yesterday, the bushing screw snapped off in the trac bar again! For the most part, even though I have a lift and over sized tires I am doing road driving but also drive through some pretty heavy snow durring the winter. I haven't realy done any off roading except for some small mud holes so the abuse on my front end has been minimal. Can anyone think of any reason why this would happen twice within 14 months? My mechanic suggested going to beefier parts but I don't think that it will be possible without getting something custom made. Is there something else that I should be looking for that might be causing this to happen? Would posting pictures of the front end help?
