Gday
I have a HSP tornado, which is just like the rancho.
I have upgraded the motor to a OFNA .32 bigblock.
At the moment I buy all my parts from www.exportpro.biz and buy rancho parts this is the link straight to the model [link=http://www.exportpro.biz/accessories/spare_part/part_list.php?select=truck_g004]spare parts for rancho[/link]
Now here is my problem I inspected the diff gears today and the Driven gear has a fair bit of wear on it.
The pinion still looks ok but I haven't pulled it right down and inspected it..
Now is there a stronger gear that i cna buy to replace it from the standard or do I have to stick with the standard one?
Any other pointers to help strenghten the truck up would be great....
