What is the easiest way to remove & replace a front differential in a 2003 Trailblazer
Hello Cheryl Finely, there really are no tricks to replacing this part. Some of the suspension needs to be removed to remove the axles. Also the rack and pinion will need to be removed. There are basically a lot of parts to remove and replace. It takes an experienced mechanic about 4 hours to do the job. If you need more information just let me know.
