I'm trying to get a good idea of what i should replace while i have the engine apart for my rear main seal. i'm getting new motor mounts/shocks and replacing gaskets related to turbo. i was wondering if it would be a good idea to replace the bearings while the crank was exposed or if it would lead to big problems. i'm looking to keep this under $500 in parts and am at $130 after mounts/shocks and the gaskets i talked about above.
