Did you modify front pinion bearing on diff? Im wondering how it will handle 175 ft lbs all at 90 degrees to the original…
Hey- a real reply 🙂
Originally I did nothing with the diff except replace the seals and put it into service. (it came out of a ’84 celica GTS from a pick and pull with unknown miles) About 7,000 miles and a little over one year in the pinion bearings did go out. I attribute that to their advanced wear to begin with, and the fact that I had removed and re-torqued the pinion flange. On these diffs as it turns out there is a crush sleeve that can only be torqued once. This meant I over tightened it and this probably did in the bearings.
The diff was rebuilt with a solid pinion spacer and has been working fine since, another 14,000 miles or so so far.
The side load is/was a concern to me as well, but consider the pinion gear itself also generates a very strong side force due to the right angle hypoid gear engagement. because of this the pinion does have tapered roller bearings on either end, which can handle a lot of load. And even in a normal install, the front bearing has to support a heavy, and probably somewhat unbalanced drive shaft. Basically I am pretty sure it will continue to handle the load.
