I bought this truck with a shake in the front end at times. You will be driving down the road at 25 or 30 and hit a bump and the front end was getting this horrible death shake. If you slow way down it would stop. Someone told me it was bad heim joints on the pan hard bar so I replaced them and went for a test cruise. Once I got up to about 25 to 30 again and hit a bump it started the shake again. Can't figure this one out. Yes I did a search before I posted and did not see a problem like mine or a answer that would fix my problem. Sorry if it has been posted before and did not find it but please help.
