I have a 2009 Silverado 1500 Ext Cab LT 4wd that I bought new in late 09. I have 72k on it but being in the north east I’m dealing with the typical corrosion issues. The known list of what’s wrong is as follows: -Transmission lines are corroding and starting to leak at the rubber connections. -ps lines are corroded and leaking. -Front differential left output shaft leaked and is wobbly. -typically corrosion starting on the rear wheel wells. What else can I expect to go? Sent from my iPhone using Tapatalk

Not hearing a grind just a clicking noise from the output shaft but will confirm by putting it in 4wd. I checked to output shaft cost with GM and it ain’t cheap. Are they available aftermarket?

I noticed a clicking noise coming from the front end of my 09 4wd 1500. Put it on the lift and discovered the driver side seal leaked and the output is sloppy when I wiggled the half shaft. Is this common? Is it typically a bearing or are there other hard parts that typically fail? Thanks in advance for any input or advice? Sent from my iPhone using Tapatalk
