Why is my agitator not moving fast since I replaced the dogs?

I don’t know if this we’ll get answered. ButI need serious advice. However, I have an older model top loader washing machine that I just replaced the dogs in and I put her back together and the thing isn’t agitating like it did before I replaced those dogs. My clothes aren’t clean and I actually can’t look in because my door lock is actually under the top! It’s a nice washer that’s done me wonders, however I have been hearing a bit of a humming when it first started. But she still spins and times and goes through every cycle except that darn agitation! The top barely moves so I can’t imagine what the bottom is doing! But I’ve say I stuck my arms in the there and took the bottom agitator and moved it myself and it felt free. So I’m lost. Please please help me. I hope it’s not the motor!

Also I did just have to also replace the locking mechanism for the lord bc it wouldn’t drain or anything once I did that it started right back up.
