So the differential gear oil should be 75W-85 now? What is the now under warranty referring to?
75/90 was for temperature range below a certain temp and straight 90w was for higher temps originallyque?
The FJ has a true mechanical locking rear end, there is no clutch pack involved. No, do not use LSD additive: not needed, no "benefit," extra cost, etcWhen you guys change the diff fluid, do you put the diff clutch pack additive in as well?
I have the LSD rear....4X2.The FJ has a true mechanical locking rear end, there is no clutch pack involved. No, do not use LSD additive: not needed, no "benefit," extra cost, etc
The heavy duty synthetic lubes I use specifically do *not* use LSD additive. For many HD trucking axles, the use of such additives is prohibited due to less gear tooth protection, increased spalling, etc
This is the shop manual section on the rear axle. Note the shift fork, and sliding splined collar
seems strange to me, that it was 75 90 someone prove to me a .5 difference does anything? i'm with stupid:iamwithstupid:
Again, please refer to the shop manual section I posted, it applies to both 4x4 and 4x2 versions. What Toyota calls "auto LSD" is - in essence - electronic traction control. Engine torque is modulated and the brake is applied to the spinning wheelI have the LSD rear....4X2.
