Question by puddytat12345 posted 7 months 3 weeks ago in 2002-2005 (3rd gen)

A few days ago I was driving when i accelerated suddenly my SUV started to pull like a huge gust of wind had caught my truck and blew it to the right and it continued to pull like this till I slowed down It continues to do this when I reach certain speeds and it's not just high speeds. I could be going 40mph and this will start happening. I have new struts, I had the upper ball joints changed and all 4 tires are new.  I know I need an alignment because my steering wheel is very off center but could that really be the issue to cause such a drastic pull? I also need to mention that I hear a loud air escaping noise coming from the passenger side of the vehicle when I stop and especially when I park and turn off my truck almost like your turning off your a/c but that's not working right now either so I don't even try to turn that on.
