OK so today I went to sit on my blaster and I hear this squeaking noise when I sat down
So I got off and pushed it side to side and it wobbles so I looked down near my engine and the whole piece in the middle that the bolt goes through is gone the piece to right of the one with numbers on it . I'm going to check if the bearings are shot too. Does anyone the the piece that broke is vital to have or am I gonna go through the a lot off bearings
 
get us a picture so we can see what you're talking about

right next to the numbers on the right you can see where it snapped
 
That is your engine case


sure is !

I'd be tempted to find a used/abused/cracked case for cheap, cut that piece out, grind it to fit that area and have it professionally tig welded back on.

the other and best option is to replace that case halve, which happens to be the side that breaks the most from chain whack, and is getting more expensive by the minute as they're getting harder to find these days.
you also need a complete gasket set and new main bearings/seals at least :(

Uuummm, When I look at that pic, I see the right, easily available, side broken. However, might find damage to the left side when you get it apart. I would wonder what caused that. Never seen or heard of that happening.
 
I would guess that the swing arm bushing are toast. The engine is tied in to the frame in the front so if you move the bolt in the back it's bound to break something. Cast alum. Dose not really bend it just breaks that is the rt side case though

I'm pretty sure it's been cracked and the bearings are just shot for 45 bucks I'll replace them and see if the wobble goes away

Is this the right side ? Cause I'll order asap
 
yes, thats a right side
I pulled the swing arm and it defiantly needs new bearings but the some pushing a are stuck and bearings any suggestions on how to get them out. So far I've only used a screw driver and a hammer

Get a socket that fits the inside diameter of the tube that will sit on the bearing. Then use a long extension and pound them out. Heat helps too. Or even a blind bearing puller.
 
There is a reason that case is only $20!!

Notice the missing piece? Hopefully you find a way to fix that, or cut off the back tab like mentioned before
