At Fuller’s Automotive we’ve been setting up differentials for a long time and there’s a lot more to it than just taking them apart and then getting them back together again. Things like tooth pattern, backlash, ring gear run out and flex, bearing preload and the relationship between drive side and coast side tooth patterns. In today’s automobiles there’s even more to think about, like locking differentials with electronic controls and automatic four wheel drive. At Fuller’s Automotive we don’t just kind of work on differentials, we do it all the time!
We’ve probably set up more ring and pinion gears than anyone around. We also have a lot of experience with racing ratios and racing rear ends. If you’re interested in custom gear ratios and locking style rear ends check with us and we’ll tell you which ones we’ve broken and which ones work. Ring and pinion gear sets are expensive so when its time for differential work make sure that the money you spend will last for a long time. The only choice for differential repair is Fuller’s Automotive.
