To the right and left of the transmission. What are the two large bushings ? Pretty close to the control arms.

 

Do you mean this one (and similar on other side)?

If so, those are the front axle supports.

 

Yes is it in fact a bushing ?

 

The FSM refers to them as (front differential) left and right rear mounts. The one on front is Front Diff' front mounting bolt and nut.

Can not find any part reference to either on any toy part website with diagrams. Sorry. Was a thread on tacomaworld (?) where a member there made them for the 3rd gen. But I don't think that guy is active there anymore. And don't think they're same part as second gens.
