Differential issue - extreme huge trouble

[irishtwincam]

My newly built differential arrived


I have a used TRD LSD whch has been broken in already.
The CWP, bearings etc are all new.

This is what I researched and was told by my diff builder.

New CWP break in procedure:

I recommend covering the ring gear teeth in the Redline Friction Modifier/Break-in Additive, and turning the pinion several times (so then it too is coated) prior to re-fitting the diff unit to the axle.

Then I recommend using a superior synthetic gear oil such as the Redline 75W90 for break-in to best cope with the extra heat of break-in.

After driving very lightly and slowly for the first 10-15 miles, you must let the differential cool for at least 2 hours before proceeding.

Drive very easy, light and slow (30-40 mph is OK) for 500 miles before loading the differential (ie no faster driving/drifting). Normal gentle urban driving is ideal.


Change the gear oil after the first 500 miles! This will remove any metal particles or phosphorus coating that has come from the new gear set.
It would be even better to change the gear oil after 100 miles or so, then again at 500 miles.

After this, progressively faster speeds may be driven for short distances (less than 15 miles), but let the differential cool before continuing during the first 50-100 miles of higher loads or faster speeds.


ANY OVERLOADING OR OVERHEATING CAN CAUSE THE GEAR OIL TO BREAKDOWN AND THE RING & PINION WILL WEAKEN.

So 15miles uber slow
100 miles <30mph (change oil)
400 more miles <30 (change oil)
50mph for 15minute intervals, then cool diff for 2 hrs (100 miles)
Change oil.

~600mile break in.

This is the break in for a new LSD core.

Did you do any break in?
