Limited slip rear diff. Gear oil suggestions?

[xsacta]

Last week my '05 TRD Sport's rear diff started to groan on turns for the first mile from home, so I know it's time to dump the original lube. 18K miles. I usually swap it out much earlier, but I just didn't get to it this time around. I'm hoping to get the right stuff in without experimentation. Any suggestions for a first time is the charm LSD gear oil swap for this particular rear? Something conventional (brand) is fine, a synthetic blend and additive.???

Thanks!!

I used Mobil 1 Synthetic 75w-90 Gear oil with one full tube of Trans-X LSD Friction Modifier. Worked like a charm!

Do a search...there are tons of threads on this topic.

same with 2 full tubes.

I used Mobil 1 75w90 synthetic and it took 2 full tubes of friction modifier to keep my rear from binding. Many people use it and have no problems at all, however there have been a few people who have had problems with Mobil 1 synthetic gear oil.

Here is a thread that I started about a week or so ago when my problem started, there are some good suggestions for other brands as well:
