Are their any particular brands that are better then the Advanced Auto parts? Im about to replace my Engine and Transmission mounts just for good measures and i wanted to make sure there isnt anything better out there...

Im also wondering about a LOUD popping noise when i put my car in 4 wheel. It will run all 4 for a minute (i can feel it) then the whole car JUTS like a mother ####er and goes DOO'M and the front end gives out for a second. sound like the hubs? u-joints? or transfer case?
