jstatham 27 Posted May 31, 2022 Well my Daughter let her friend drive her ATV and she lost control and hit a tree. Luckily nobody was hurt. It took me a while to get it loaded up on the trailer and get it back home. I took the tire off and it looks like to me the only thing that got damaged was the front rack and up and lower ball joints. Does anyone have any suggestions on how to tell if the control arms are bent and do you see anymore damage. What ball joint would you recommend? The tie rod looks OK from what I can tell. I am going to pressure wash tomorrow and try to tell what is going on. Any help will be greatly appericated. Share this post Link to post Share on other sites

This is a 1996 Foreman 400 with the 450 head. I just completely refurbished it around Christmas and added the disc brakes. I am pretty sure you were helping me out then as well. Any advice for straightening out the rack. I was going to use a chain or strap and hook it to the rack and a tree and use reverse and the throttle to bend it back.

Fishfiles 20,147 Posted May 31, 2022 By using a 450 head on your 400 you are de-powering your engine. The 400 head has a smaller combustion chamber than a 450. The 400 head would have given you more compression. i have a 450 with a 500 jug and piston and a 400 head on top Share this post Link to post Share on other sites
Fishfiles 20,147 Posted May 31, 2022 This is the 400 head and the 450 head , all the valves ,springs , etc , etc , the only difference is the 450 has less compression than the 400 Share this post Link to post Share on other sites

jeepwm69 7,751 Posted May 31, 2022 That sucks man. When my sister and one of her idiot "friends" hit a tree on my 500 back right after I bought it new (had 600 miles on it) it busted the plastics, bent the front bumper and rack, tie rod, wheel, and frame. I replaced the tie rod, bumper, front rack, and wheel, and it was only after getting it all back together that I realized the frame was bent too. Looking at the frame itself I could never see anywhere it was bent, but the whole machine looked "off". I eventually bought a used frame and swapped everything over. Only after I put the stripped frame flat on the ground could I see where it was twisted/warped from the impact. Hopefully your machine will fare better. The guy driving my 500 hit a tree at about 30mph trying to jump a hill on it. OEM ball joints are just as cheap as aftermarket, and are better quality. I'd replace the ball joints and put it back together and if the arms or frame are bent you'll be able to better see it when it's all back together. Glad no one was hurt. Wheelers can be fixed. People aren't as easy. 1 Share this post Link to post Share on other sites
jstatham 27 Posted June 3, 2022 I got it back together tonight and was able to bend the racks and pop the plastics back out. I did notice the frame was a little bent on the left side where the rack bolts up. I did notice the drivers side inner cv boot is ripped. Any recommendations on what boots to use? I can tell the steering is a little off but I am going to look at this weekend and see what I can figure out. Share this post Link to post Share on other sites
toodeep 1,760 Posted June 3, 2022 All Balls for replacement boots. They are exactly OEM spec (you can still use oem clamps), cheap, come with grease and universal clamps if needed. Share this post Link to post Share on other sites
