I recently replaced my HB because it was seperating. After getting it all together, I now have a vibration noise when accelerating from a dead stop. Kinda sounds like a tire rubbing the fender. No vibration in steering, on my feet, butt, anything. Runs smooth. No engine light but I notice my oil pressure runs higher.. like at 80+. But it drops to 40 then back at 80.. does that while I drive. I'm stumped... any ideas???
