preparing for changing differential any tips, tools, parts list?
switching the 2.73 gears to a 3rib 3.42s on my A4 C5.
will also switch a worn tie rod end and hub and transmission filter.
just wanted to know if there was any tips you guys have, tools to make it easier? anything i must look out for?
or things i should order from Gm Parthouse to skip the dealership prices
any other things i should check out or replace/upgrade?
also what trans fluid is the best? normal stuff or high mileage? (has 105,xxx miles)
also will get tuned soon after.
thank you all for the help
