Hey everyone my runner starts to shake after or whenever i hit 75mph. What can be the cause? Can it be my alightment?

Sure. Could also be unbalanced tires, improperly inflated tires, worn steering components (tie rod ends, ball joints, idler arm). An after-market steering stabilizer always helps too.

could be that, could have a tire thats a little off from the rest (pressure), maybe some other stuff....I have the solution tho, don't go 75...go 70 or 65. You'll get better mileage thats for sure.

If it's only within a certain speed range, it could be balancing of your tires. I had a similar issue awhile back when driving 60-70 mph; it turned out to be the balancing. Some places do a high-speed balance. This is not cheap and costs around $50 for all tires.

Check your shocks also you could have a rear tire bounce.

Start with the small stuff, check tire pressure, get wheels balanced and rotated while you're at it and then go from there. If it still does it after all of that, make sure it wasn't just the part of the highway you were on, there is a 2-3 miles stretch around here that has some serious bumps and stuff and it shakes, rattles and rolls all the time when I'm on it. Not to make you sound stupid, but a lot of the time you just don't think about it.
