yes....the DANA 30 & 44 axles have issues if you do hard wheeling/crawling with oversized tires....my tubes and gussets should arrive tomorrow and it's no easy task, but I say better safe than sorry! you have to remove brake assembly, axle shaft, etc... drill holes in the axle tube, slide sleeve in, plug weld the holes, and reassemble then weld the gussets on the "C's". it's a lot of work like I said, but it's a lot cheaper in the long run than a new Dana 44 front axle. I have a 2007 rubi that will have a complete poison spyder build plus offroad evolution control arm skids, 44mag sleeves, and C gussets. I plan on running 37's and I'm making darn sure to do my research for a proper build to avoid future issues. it's expensive, time consuming, but well worth it in the long run to build it right the first time!
