I recently rebuild front differential of X5 e53. The diff was TYP-174. The problem was - there was noises , and the diff has already been "repaired" by previous mechanic. Here's some tips for differential "rebuilding". First - just before removing the unit from the car measure the turning preload of the pinion. You don't need to know the specs -this is just a quick and dirty test to try pinpoint the nature of problem. If you read 0 Nm(i'm European) then 90% chance your problem is just excessive bearing wear. If you got reading above 0, then maybe the differential wasn't set to specs before , or there's gearset geometry or geartooth problems. Check for excessive runout at the pinion flange. Before removing the gearset from the housing check the ring gear for runout. Measure and compare backlash of EVERY GEAR tooth on the ring gear. Difference from the lowest and highest backlash reading greater than 0.050mm/0.002inch indicates a problem with geometry. When disassembling remove bearing caps with hand tools to "feel" if some bolt has loosened and thus contributed for the current problem. Backlash/freeplay is needed because gears expand from heat but you still need the extreme pressure oil to be able to lubricate between the gears without separating from the face of the gears like if the backlash becomes 0. Too much backlash creates noises, and latter - vibrations if not addressed. If changing PINION BEARINGS you must take in account "pinion dept" if you're not setting the pinion depth to factory spec. Measure the current pinion depth(that is if you know for sure THIS IS the correct depth, otherwise you risk having to redo the whole thing again if the final pattern check directs a change of pinion depth either inwards or outwards.) It can be done with special tools , or straightedge and depth micrometer/vernier caliper. You need to know this because even if you keep the current shims , the new bearing could be different thickness because of manufacturing tolerances/variations. So if the new bearings are thicker you'll need to replace the current shim/shims with thinner and vice versa. Another tip - always set the preload of the bearings at the higher spec given. Over time , while the bearings is wearing , the preload will only get loose and looser. A tip recommended from manufacturers of specialty drivetrain aftermarket parts - they recommend if removing/installing the ring gear from differential case always to use red loctite on the bolts and tighten the bolts in 2 stages. First stage is half the specified torque .This is because sudden excessive torque could distort the ring gear flatness just like when installing cylinder heads. Another tip from aftermarket performance parts manufacturers : painting all the gears during contact pattern check/test is recommended.Then install the axle shafts and brakes. Partially apply the brakes using adjustable brake pedal depressor tool until it takes about 70nm to rotate the pinion flange. Rotate the the flange 3 or 4 times forward and backward. If you think this is not necessary , here's the explanation i got on "Pirate 4x4" forums, when i asked why is this needed. Because not every pinion-ring gearset is "nonhunting" type. Nonhunting means every pinion tooth got it's mated tooths on the ring gear. Every rotation of the gearset the same pinion tooth contacts the same ring gear teeths. If the set is "hunting" or "partial nonhuntin" the pinion teeths contact different teeths at the ring gear than the ones contacted the previous rotation of the gearset. Also this technique can help catch if there's geometry problem with the gears , that is if you before that didn't measure backlash at ALL the teeth or didn't test for ring gear runout or pinion gear shaft runout. Final tip: when changing the oil , after draining all the oil from the housing , it's recommended to lift the car first from the left and then fromthe right. That way oil that's left in the left/right tubeing would drain also. And finally my unnecessary opinion on this FORD 8.8 differential. Judging by the info from 23:30 , this unit was "repaired" before. They setup the the preloads and backlash okay, but messed up the pinion depth because they changed the pinion bearings with a thicker/thinner ones, while keeping the factory shim. Finally they run a contact pattern check , saw something is wrong , call it a day because whether or not the pattern check, they knew the preloads and backlash were okay AND otherwise they needed to redo everyting from the start again(if they even knew, what they must do to fix the problem).

my carrier unit on the left Drivers driver side was disintegrated the bearing got into the ring gear and ruined the ring gear. tiny metal shavings everywhere, I spent many hours just cleaning the differential housing, I used two cans of Gunk engine degreaser, two cans of brake cleaner, it still had tiny shavings, finally I borrowed my neighbors pressure washer, always measure your parts, the solid pinion spacer and shims I ordered on Ebay was too small, I had to order a new one on Amazon, also the pinion seal that came with the rebuild kit was wrong, I ordered Another one Timken on Amazon that is the correct one, I'm doing the final assembly now, this is a hell of a lot of work, my first time doing one. Thank for the video, it has helped tremendously.

100% agree with the other comments. This video is the most helpful, informative video on the subject that I’ve found. The terminology is now clear and the order in which they occur. I have a 2016 GM 12 Bolt that had a failed (lower/Inner) bearing. The odd thing is that the pinion shim was behind the upper bearings race. Between the race and housing. Not under the lower pinion bearing like ever other rear diff videos I’ve seen. It was destroyed during race removal. We got all GM genuine parts including a set of pinion shims. No diagram shows shim locations. I suppose I will have to match up the 1 shim and place it in that same location. But I can’t help but wonder if that shim location is what caused the bearing to fail.

Regarding the pinion bearing mismatch...normally Ford axles aren't painted from the factory. They are bare steel and usually surface rust quickly. I'd wager that the axle/gears/differential has been worked on before your ownership by someone with either substandard experience or tools and didn't get things back together correctly in the field. They may have inexplicably partially disassembled the axle to paint it. Both Koyo and Timken have excellent quality controls, neither should have failed if they were installed correctly and the fluid was changed often. Severe usage would negate all of the above - being a Mustang, that's always going to be a factor.

Hey, if my goal is install a LSD, which steps of these can be skipped? I wouldnt need to take out the pinion, or would i? Because maybe the pinion depth has to be adjusted with the new diff carrier. Im not sure how easier would be or if its exactly the same process as changing gear ratios.

New crush sleeve every time. You can reuse the ring and pinion and just do bearings but be aware that if the R&P is the source of noise, it's still going to be noisy when the axle is rebuilt with new bearings. Once you have a wear pattern established in a R&P you can't change it. You should be able to reuse your stock shims for everything.
