92 XJ 4.0 auto w/ 123K, "knocks" when turning corners or at times when accelerating from stop - and pulls left when braking at maybe more than 40 mph? Tires are all inflated properly, idler/A arm bad?. It has limited slip rear that I serviced approx. 3-5 K ago and I added the factory ltd. slip additive. Also of course it just started leaking coolant from front part of radiator? Of course it's wifes that I drove 360 mi rd trip this holiday weekend and all has started maybe 1 month ago except coolant leak. I'll find leak, it's been pesky, thinkin orig. rad. due prob. for change, I just did upper & lower rad. hoses a few months back. (I put 3 core GDI in mine/identical Jeep w/o posi ,2 yrs ago.) Rear diff is full. Also think there is a "hum" somewhere in driveline, checked ujoints seem fine, but will drop shafts tomorrow to check. Thanks guys for any hints that may save me time, Heinz
