Can someone look at this picture and tell me what the part is called circled in red. I think I need a bushing for that but I can't find one anywhere. I have searched for everything but nothing. I know its a mount for the diff but maybe someone knows exactly what it is so I can find one. That diff in the pic is not mine I just found it on the net. Thanks.

You should be able to use www.toyodiy.com and look up the parts on yer truck. Without all the vital information, it's gonna be too much effort (guessing/hit or miss) on my part to come up with a part number fer that part. ;)

Thanks for the link BamZipPow, very helpful.

BTW, I found a part number for the stopper (bushing) but only show a bottom one and not a top one. Can someone verify if there is 1 bushing in the bottom and one on the top where the bolt goes thru? Part number for bottom one is 52283-35011. Some diagrams show a top one and some don't. The top one shows discontinued everywhere but the number was 52282-35010. Thanks.
