While replacing my ABS speed sensor today, I noticed the passenger side rear wheel seal is leaking oil.
When I look for a replacement, I see I have two choices, one for 9.75" rear and one for an 8.8" rear.
The metal tag on the diff. cover is stamped:
3 55 88 0A07
Is it safe to assume it is 3.55 ratio and 8.8" ring gear size?
