So it startes when i took the wk swimming. Threw some codes and needed to replace the abs sensor. I bought the part laat week and still havent installed it yet. ( still throw codes everytime i turn it on). Then the rear was acting funny. Like it wasnt engaging correctly when i turned it on and drove. But only when i turned it on. Changed the diff oil last night. Sat overnight in the garage. I have driven it twice today with no rear end problems and threw no codes. Whats going on here! Im positive the diff oil wasnt the problem
