Vehicle: 2004 Nissan Frontier Crew Cab 2WD 3.3 V6 First off, any help much appreciated. Last week, I found my front drivers side tire flat. So I used a can of Fix-a-Flat so I could get to a tire shop and make the repair, which was a patch. A week later, I my vehicle starts to violently shake during excelaration periods, then magically disappears when I hit 50 and above... So, is this an alignment issue or an issue with that front drivers side tire that was patched last week?
sounds like when they broke down the tire they didnt balance it correctly, get your front tires balanced.
