Why try to repair something that isnt broke, I would fix leak and send it down the road, not "ALL" bearings are failing, the upgrade kit is still "NEW" and who knows how long they will last?? If you are planining on keeping car for a long time, then maybe worth the security and investment, but to resell for a profit or flip this car, I wouldnt touch it.
If a buyer wants to buy your car, they'll buy your car.
If not, they won't.
The IMS bearing won't be a factor at all.
Save the money and spend the Labor on detailing or cosmetics and you'll get more bang for the buck - car will sell faster too!
Cheers!
