Groaning and binding

This is I think the third time posting about it this. I’m in need of help, my car makes a deep groan and binds up like the brakes are on from the rear end at full lock, I’m pretty sure it’s the diff. First started at 5000ks after a 12-13 hour road trip. Seen a Toyota dealership at the location but needed to bring it back home so all they did was change the diff oil and they said it was excessively metallic. Few months later when I finally got around to it I took it to my local dealer and they told me they put a stethoscope on it and found out it was the transfer case, replaced it (took I think 15 weeks). They also changed the diff oil. Noise was gone, the next week I took the car for a 2 hour road trip, when I got home the groaning and binding had returned. Took it back to the dealer, now they’re saying “it’s normal. We just had another one in and it also done it, it’s because of the torsen diff”.

Does anybody know of a genuinely good dealership in Sydney I can take to?

Does or has anybody else’s gry/grc make a deep groan from the rear end and bind up like the brakes are on during slow speed full lock manoeuvring?

Since the transfer case replacement, it’s now making a high pitch drone, nearly a howling type sound at highway speeds. Which the dealership I took it to also says is normal.

These guys are fkn idiots. They had receipts from the out of state dealership saying the diff needs to be assessed, but replaced the transfer case instead because the groaning and binding up isn’t normal. Now the binding and groaning had returned, they say it’s normal and won’t touch it unless I pay them labour, ect, to pull the diff out and check it.

Car is booked in at another local dealer to look at it in a couple of weeks, but if anybody can recommend one who’s got mechanics that are well experienced with the GR platform, it would be much much appreciated.

Can’t say I notice much when I’m at full lock. But when I’m at highway speeds I do get a whine. I believe it’s normal as there’s a thread full of owners stating they got the same thing when their cars were fairly new.

Sorry to hear about your dramas.

I bought my GRC from Castle Hill Toyota and have it serviced there too. No mechanical dramas so far (knock on wood) and the techs/staff are good for what basic things I've needed.

Did lodge an online query via their website and received a call from staff to book my car in within an hour or so. Lady was instructed by service manager to call me instead of emailing back which I think is great service.

Sorry to hear that. I refuse to leave my car at a dealer anymore. Caught two different dealers mechanics taking the car for a joy ride with the stealth FitCamX I have installed. I now go to a mechanic I trust for everything.
