Hello everyone,

I have a 2021 450L that used to steer very steadily, with a good amount of pressure on the handlebars. I had it serviced by a mechanic, he took it apart almost totally. However, after the service, the steering was very unstable. Like the handlebars were loose. Normally the steering reacts immediately, now i can pul the handlebars 15 cm to each side without steering. Could not drive harder then 30 km/h.  Then i took the 450 to a wheel alignment shop and they aligned the wheels. This improved the situation but it was still not as before the service. Yesterday the machine had again the same problem after a month... Does anyone have a idea what could be wrong or what should be done to get the steering back how it was? id appreciate any advice. Thank you

First, why would you need to take the power steering main unit apart for service? Did it have a problem? They are not repairable and changing anything in there especially the torque sensor will have repercussions. Clearly he didn't assemble it correctly so he needs to be held accountable...to either repair or replace the unit. By the same token, he could have just something unplugged so do check that first. 

Thanks  NMKawierider, for your help.
Maybe a stupid question, but does a 2021 Cforce450L-au  has power steering?  I dont believe the mechanic toke apart the main unit. With "he took it apart almost totally" i ment al the parts that need maintenance. He took of al wheels to lubricate parts, that i know. Where do i look for this?": "he could have just something unplugged so do check that first". Thank you so much for your help!

Oh..450, it may not. I understood the steering now has play where it once didn't and steering it was different. The 400/450 does not have PS.

So then its an other problem.....
" I understood the steering now has play where it once didn't and steering it was different".
This is correct. I made a video:

Maybe then its more clear what the problem is...
Thanks again!
