Need to pull a 126 differential cover. In the lower left hand corner is an arm-support with an upper/lower rubber bushing. A bolt goes up thru the bottom of the lower bushing.
A Torx T55 bit seems to fit fairly well; however, the 126 CD-Rom refers to it as "serrated". Reading through other posts here, it seems there's a difference between TORX and SERRATED. The metal on the bolt head appears to be VERY soft. I've tapped it a few times with an impact driver to loosen it and have tried the gently loosen it with a Torx T55. It's not budging.
Would anyone know the correct socket to use here? Thanks for your time.
