If you follow the instructions exactly, then no worries. However, the instructions do not warn you about the four wheels. Be careful when you attach the four wheels because parts B09 and B10 are not the same as parts B18 and B19. Follow the instructions carefully. If you look closely, you will see a difference between the two sets of wheels and they should not be mixed together. B18 and B19 are the front wheels while B09 and B10 are the back wheels. Hope this helps.
My friend just recently built a Rubicon Jeep and got two of the wheels switched. He cut all four wheels from the sprue at that same time. He then glued all four wheels onto part B40 without noticing the subtle difference between the front the back wheels. As a result, he got two of them placed wrong, so now he has one front and one rear wheel at the front of the Jeep, and one front and one rear wheel at the back of the Jeep.
