Hey Scotty, Love your videos and your skills. You are last of a dying breed for sure. I have a 2008 Honda Fit base model bought it used 4 years ago with 29k miles. It now has 108k miles all highway. No racing because face its not fast. It's a daily driver in S. FL. I drive 104 miles a day round trip. I am having vibration issues with the front end. I replaced struts and shocks, I went from 14" steel rim to 15" light weight (really to get better tire selection) put Michelins with what size tirerack suggested, which is still in factory spec, aligned, balanced and rotated. I'm not afraid to get my hands dirty so let me know what I should do next? Lower balljoints, CV joints, motor and tranny mounts?
UPDATE!! After further research, signs were pointing to low spot wheel bearings. Now I really had no time to do this over the weekend. After watching more clips of Scottys one clip came up about a bad balance job. I had time for that so I said what the heck I'll try it. Told tire kingdom my issues. They redid the alignment and balanced all wheels. I didnt have time to get on the highway after work was done to the vehicle, so I wasn't sure if it worked. I drove the vehicle this morning to work, which is all highway. All vibrations are gone!! When picking up the vehicle yesterday they did say it seemed as the alignment didnt hold.
It was a couple of thousand miles before hand. I figured doing all that would alleviate the problem. I could feel bad balance at 20 mph before I did everything. After all said and done I would say faint vibrations around 65mph. No engine done besides me changing plugs and belt so far. Now over this weekend the highway was crazy, so I was around 90 before I knew it. Gradually accelerate not pedal to the medal.
Need more info. Did vibration start before or after you replaced struts, shocks and wheels? When does vibration occur-- at idle, highway, 35-mph, e.g.? Any associated noises? Is it your engine or suspension vibrating? Have you had any work done on your Fuel Injection system?
