The 06-08 models have non-serviceable IMS bearings, however we do recommend removing the grease seal so that engine oil can properly lubricate the original bearing as outlined here:

That said, there is a company that offers a product that will bore out the IMS access hole to allow extraction of the bearing, but that's a horrible idea. You'll be introducing all kinds of debris into the engine. We've seen several engines suffer catastrophic failures after having this procedure carried out. The only way to change out the bearing is to tear down the engine. Our IMS kits for the 06-08 models utilize an adapter bushing that then makes the IMS bearing serviceable in the future without engine disassembly.
