Not long ago I posted about my 8.8 out of a Fx4 Level II with a bent axle shaft. That's been resolved! However there's still a few things that I have minor concerns about. The R7 in this particular rear had a Torson LSD, instead of the clutch style limited that I was expecting. I'm not bummed about it, but I really don't know how to feel about it.
Onto the concerns; It seems louder in the rear than I was expecting. They say that a torsen shouldn't be any louder than a standard differential but I just can't see how it's possible to be just as quiet with all the worm and spur gears inside of it. Is it normal for them to be a little louder than an open diff? It kind of sounds like I have loud tires. Also the torsen doesn't seem to lock the way I would expect a LSD to lock. From a stop on gravel it will spin both tires for about 3 feet and just let one wheel spin after. On wet pavement from a stop in a turn, it seems to act more like an open differential. I'm not very versed in torsens so I'm not sure exactly how the torque bias works. When I think limited slips, I think both tires spinning and whipping me around in circles.
My other concern is a rumble that I have around 60 to 64mph. I didn't replace the wheel bearing from the bent axle shaft, it looked fine and felt fine so I ran with it but I do have a replacement bearing and seal should I need to replace it. I checked the pinion and it doesn't budge up or down, side to side. The rotational free-play seems normal, about what I would expect. I recently replaced my driveshaft u-joints. Any ideas?
And my final concern is a slight vibration at speed when I push the clutch in. It didn't do it before the swap, again, checked pinion and u-joints. There's no other whine or noise associated with it. I don't hear it when coasting with the clutch out or accelerating, just whenever I push my clutch in and disengage. That one really has me going for a loop.
Any ideas?
