This was a first for me. I can change oil, change tires, change filters, brake pads, windshield wipers, light bulbs and fuses, but the transmission spare part was new. A few quick web searches and I found a video on You Tube. If you can change brake pads, you can. Jack, torque wrench, 13mm, 8mm, 13/16 inch sockets and jack stands, plus brake cleaner, grease, rags and patience is all you need. I swapped sides for the first time following the video on YouTube and it took less than an hour. And now I have a 4x4 and no more annoying grinding/whining from the front. Great product! Exactly like from the factory. Moog has never let me down!
