I think it's a good idea to check it. Simple and accurate way is to jack up the front so you spin the wheels and scribe the tires with a long handled screw driver or some tool like that. You can Use a jack stand to rest your tool on and hold it steady. Then put it back on the floor and bounce it and roll it bath and forth a little to get all the tension out of the suspension, then just measure to your marked line front and back. Be sure the wheels are straight ahead.
