Rear Main Seal use the tool required to center it
Do yourself a favor and remove the seal before installing it. Use the rear main centering tool then reinstall the seal otherwise it will more that likely leak as it won't be centered perfectly even tho it kind of centers it self with the seal.that's not good enough some people get lucky but not worth the chance of it leaking again and have to do the job twice.
