Have a 08 Grizzly 700 EPS. The power steering does not work and thinking about fixing it. Found a halfway cheap used one and just want a heads up on how big a job. If to much of a hassle will leave it alone. Plus putting used electrical parts on the job needs to be not that bad. lol
Thanks

Do you have a copy of the service manual? That should give you a good idea of what it will take.

My opinion without looking at the service manual, is that it should be very straightforward. Heck, if guys are able to put aftermarket power steering kits in, an oem drop in should be no problem.

But taking a step back first, have you tried diagnosing what's wrong with yours?

Changing it is not that bad. Remove front plastics is probably the worst part about it.

But I 100% agree with wheelsquad above. Did you actually troubleshoot it first to know the power steering motor is the issue?
I do know yours is a 2008, which had an issue with premature power steering motor failure due to a vented motor (2009-newer models had sealed motors), but you should first be 100% sure the P.S unit is the problem before replacing it.

Agree with...wheelsquad and dezz..
What's going on. EPS light on or off? Checked the fuse? With the service manual the diagnostic mode can be use to find some of the possible problems.

Code Shows EPS Torque Sensor. And with research that part is not available . Was just hoping someone had a few pointers and or suggestions on how to make the switch if it was not too bad.
Thanks

There very well might be some guys here that have done the swap. Might just take a couple days and bumps to get someone to notice.

My advice is just follow the service manual.

While you have it torn down that far I would...
Replace the steering stem bushing
Adjust the valves
Dielectric grease all the connections as you re assemble.

Post back
Good Luck!

Did you happen to switch out the cdi box to an aftermarket by any chance? Just wondering, because when I did for my 2014 grizz 450 eps, it kept my eps from working because it was not compatible with eps versions of the fourwheeler. I didn't know for about 2 months, and during that time I tried everything to get it to work and it turned out that it was the cdi box. I bought an AMR racing stage 3 cdi, and that was issue. I put the old one in, and bam, eps started working again. This might not be your issue, but thought I'd share just incase...

Thanks for bringing this up again. I remember your thread about that.

I just had my EPS light start staying on; on my ‘07 so I thought I would post my findings on a couple threads in case it helps someone. Not sure if you’ve fixed your EPS yet. Here’s what happened to me. I was flushing my cooling system and sprayed water all over the place-EPS light came on with engine running- tried the WD40 down the eps breather trick- checked eps fuse and all related connectors- didn’t help- read about the diagnostic “ code flash feature” realized I had downloaded a full serv manual a while back and never thought to check it for diag info. Anyway, got a code 21 which is speed sensor. I knew I hadn’t done anything to the speed sensor wiring to cause a code to set so I decided to try just clearing the code to see if it returned ( automotive control modules set erroneous codes all the time ). Cleared the code and it DID NOT RETURN. The procedure is outlined in the service manual. Hope this might help some of you. YOU CANT CLEAR THE CODE BY REMOVING A BATTERY CABLE:) You have to do it as outlined in the service manual. These are the steps. Key on-disconnect diagnostic wire ( blue with gold dots I think )( located right behind eps controller under CVT air intake) - ground male side of connector to eps module case within 5 sec of turning key on - after another 5 sec the eps light in the cluster will flash out your trouble codes - NOW to get into history codes ( where you want to be when you clear codes) you disconnect and reground the diagnostic connector AGAIN. Now you’re in the history code section and when you erase the codes in this section it clears all active and history codes... NOW tap the grounding wire to the eps case three times and codes will clear. Hope this might help someone. This thread is old but if you’re reading this and have EPS TROUBLE. Try clearing the code before you do anything else, it might save you a bunch of work.!
