Sorry I haven't been on for a while.
The first transmission was a Peugeuot, we did swap in the AX15. I don't have a body lift, the suspension is stock but I am only running 30" tires. Like I said I haven't taken this one out yet, when I do I will take pictures of it and post them. It might very well be something I am doing when I put them in. I didn't know about the vents.. I have been playing in the mud so much with the vent being stock, it sat in a coolie for about a day so that could be a huge factor.
Thanks for all the help, I will get back to you guys when I take it out, and take lots of pictures.
