Hagar sez : VW and BOSCH must be using Gorillas and or Lock-Tite. or both. So I told you all long time ago ---go get a --IMPACT driver ( I use a 3 /8 inch) The type that you hit with a BIG hammer. NO air or nothing needed.. Alternators ---Starters or IP's to take apart ----man do they work or what ?. A good one is about 15 dollars. Hagar.
