Anyone running a stock drive shaft on a V6 4ruuner or truck with 37=40" tires. Are stock shaft pretty stout? I have one built and I think she is bent...bad vibration on the road. V8 yota behind me today said she was wobbling pretty bad. I just wonder it it could be a pinion bearing? The seal is leaking. I checked joints and there is no play. If you have a stock shaft or know someone that can build one for good price please let me know....
