rear brakes wont bleed spongy lever

So I put on new pads on the grizzly that was fine I got the front in and bleed and it works great. I did the rear and couldnt get a firm lever. So I ordered a master cylinder rebuild kit. still no firm lever. I installed a seal kit in the left rear caliper. Still no firm handle. I pinch the line after the master cylinder to see if it is working and the lever gets firm so the master cylinder should be good right?
I pinch the rear brake line on the left caliper with the new seal kit and it is firm handle.
I pinch the rear line on the right side and it is spongy. So the left rear caliper has to be the issue.
I just installed a seal kit in it and the piston slid right in with no force. I have ran plenty of brake fluid through it by gravity and by squeezing the lever, opening bleeder, closing bleeder and then releasing lever and repeating.
Any advise on this thing?

bad wreck need advice

2014 grizzly eps 450 rolled about 3 times, broke the steering hub/knuckle, bent the lower A arm, bent the adjusting sleeve, pulled the cv axle out of the differential and pretty much destroyed the cv joint.
in the pic i uploaded the knuckle with the vise grips clamped on it at the break when it rolled. the other knuckle is supposed to be an exact replacement. you can see the different angle between the two, is that one bent and broken i didnt figure cast iron would bend.
ive replaced the lower A arm and tried putting everything back together and i can get only 1 of the lower arm bolts to line up the other is almost an inch away from the bolt hole. the upper arm looks good i cant see anything bent there. the frame looks good at the lower mount area too. if i use the broken steering knuckle everything bolts or lines up perfectly. any ideas? i cant even get a new knuckle from yamaha till march 17

Assessing Crash Damage

Hi all,

I had my first crash yesterday. Lost traction around a corner on a logging road and went into the bush going 75 km/h. I was launched off the machine and went flying into the woods, somehow missing the ash tree in front of me and landing on a pile of leaves. I’m extremely lucky. The bad news is my 450 Grizzly smoked a rock. The impact happened on my plow mount on the left hand side. After being winched out of the woods, I was able to ride out without noticing any problems with the machine.

The front grill guard is bent as is the lower A-arm and plow mount plate (plow still mounts, but the blade is now on a slight angle). Those are bolt on parts so I’m not really concerned.Upon further inspection, it appears that I pushed the frame in a bit. I have no idea how bad the damage really is, so I’m asking you for your help before I go to the dealer to have an assessment done for $100.

What do you guys think?

NEED HELP FAST!!!

I have a bit of a set back… I have a 2001 grizzly 600 its a great bike i love it best bike ive had. But i cant seem to keep ball joints in it. the first ball joint fell out at about 50 mph sending me sliding down the road and the bike in peaces. Me and my dad rebuilt it . And replaced the ball joint with a kympex a arm and ball joint since they are made together. About 2 weeks later i broke a front left axle and when i replaced it i found that ball joint bad again.. I thought ok maybe a odd ball in the batch and messaged the company and they sent another. Well today i was at busco with the fellas and once again another ball joint falls out thank god i wasnt moving to fast about 5 or 10 mph. Ive read up on this a little bit and the only thing i found was the nut backing off. But in my case the ball itself is coming out of the arm . Hoping someone can lead me in the right direction with maybe a better company or some tips …. thank you.

Rear diff, this look normal?

As some of you know, I am doing an almost full resto on all moving parts on my 660, and I found this…

Should mud/dirt be able to get in there? It was packed full, but none got in the diff, just around it. I bought a seal kit, thinking that the bearings will be fine, but this has me concerned now.

Anything else?

Have the 660 in the garage for some repairs and please chime in if you think I should get anything else:

4 wheel bearings
4 tie rod end links
Front diff seal kit
Rear diff seal kit
New pitman arm

The bearings in the diffs all seem fine, but still haven’t removed them.

Quad has 7100+ miles on it. Thanks!
