I have a 1976 chevy k10 with a 350 4bbl. I have replaced front ball joints and u joints. The truck before i replaced those parts, would have the whole front end shaking real bad. I replaced them then its not doing it as bad but still isnt completely not shaking. The fastest speed i can go without it running me out the road is about 50mph. Thats not fast enough i need to be able to get where i gotta go with out being late and its just a real pain in the you know what if your ride aint doing as it should. Yes it has a 4 inch lift kit on 39.5" tsl's but that shouldnt matter too much to make it shake so violently so if somebody could just give me an idea or what to checkout or into it would save me alot of time and money. Thanks
