  1. Hey everyone, I’ve got an 04 GX 470 that I recently did a t-case swap on. Long story short, the old case had the common problem of leaking at the o-ring seal and the thing was dry when I got it from the dealer. That, or they just didn’t refill the case when they drained it. Regardless, it damaged the case and I swapped it with a used one in my garage. However, now the center diff won’t lock on the new case. I’ve read around that if there’s oil in the actuator the thing can’t engage correctly. It’s also possible that it sat for a long time and froze. I still have the old functioning a

I decided to drain it and there was no oil— turned out to be an O-ring actuator leak. I refilled it with oil and it still made the new grinding/howling noise at speed (35mph+). The dealer bit the bullet and replaced the O-ring and told me that the noise was normal (which I know is not normal). I’m taking it to the local Lexus dealer b/c no smaller shops in my town rebuild these T-cases or install them. I’m worried that the dealer
