The link I posted may or may not be for a front mount hitch, the ads all use the same pic regardless. The one in Barneys link specifies front mount. Definitely check before buying.
The factory receiver will likely need to be removed first as it hangs under the cross member and would be in the way. When I did the install on my old 4Runner the new hitch used 2 of the crossmember bolt holes, as well as the frame holes. It's not a big job, just a little tricky without removing the bumper cover. Hardest part was getting the factory hitch off as the 2 upper bolts are cover by the plastic bumper cover.
When the new gen t4r came out there was no aftermarket hitch available for it. It's been several years now and I'm sure there is now. Any dealer should be able to tell you.
