DO NOT attempt to install the LSD yourself if you have never done any gear work. You need to have all the correct tools to make sure you do not ruin your gears when re-installing. Take it to a reputable shop and have them do it. Changing a head gasket is nothing compared to working on gears.jclaar said:I'm going with the Auburn. Is there a how-to on how to install it? I'm pretty mechanically inclined. I replaced both head gaskets in my 4.7 with no problems. I do not have a bearing press or remover, though. I don't know if they're needed. I have everything else. Also, does airram offer install kits? I only see the bearings available: http://www.airram.com/product.php?categoryid=750&productid=175. If I need to have someone else do the install, what is a fair price?
