$240 for the front differential bushings/mount???? Did they say which one is bad or all three of them? Two of the bushings are identical and cost a little over $20 a piece from the dealer. The third bushing/front differential mount cost a little over $100. Only the top bushing on my XK was really bad and that was the $20 bushing. A lot of people have been replacing those lately. save your self the money and do it yourself. I'll warn you know having just done mine two weeks ago that its a PITA. Make sure you have all the proper tools and something to press in/out the new bushings.

BTW that XK is SEXY! I dont know how you keep it looking mint especially if you take it off road.
