So like my previous post, I installed a full round of GP bushings, new ball joints, and a new bearings. Ive noticed my rear end seems to sag a touch now and doesnt really spring back up well like before.

Would it be because all of the new bushings made everything so snug compared to before?

everything is torqued to service manual spec, greased like whoa, and my rear shocks are on the furthest setting down for the most compressed spring.

I’m wondering if its because of everything snug now and just needs to be ridden a few times or if my shocks are towards life-end.

thanks.

Shocks don't support you, springs do.

Its most definitely tighter now. Probably just need to crank the spring preload up a notch or two.

If you torqued the bolts to spec but the threads were greasy from assembly, than the actual tightness/torque is much higher……just a thought….

Good point MrEd.
How tight did you torque them OP?

I torqued them to service manual spec, 40 or 45 whatever it said. I bought a digital torque wrench (coming today) because I don't trust the manual one, it was from harbor freight and a bit janky at times. I also have the cecca frame braces to put on so most of the bolts are coming out again anyway.

You may have them a little too tight. Spec is only about 35-37 lb.ft. I think.

There is no way to overtighten those bolts unless you strip them. The frame tabs contact the steel rod through the center of the bushing. That rod will stay in one place and stop the tabs from moving closer together. So even if over torqued it should be fine.

Did you grease everything on install?

Everything is greased well. Im going to re-torque everything and see how it goes. Im sure itll also loosen up after a couple rides since everything is new and needs to get broken in.

.Polaris springs are known for getting tired after a while. Got to occasionally put another notch on the preload as the springs settle in order to keep ride height where you want it. When you run out of notches, then you go to EPI HD's and start back over again at the lowest setting. That's just sorta how it works OP.

Im going to see how is does at the HMT this thursday, I definitely don't have time to get new springs let alone and install them. Thanks for the info though, greatly appreciate it and will dig into them when I get home. It is a 2016 and originals so Im sure theyre past their prime

"There is no way to overtighten those bolts unless you strip them."

Well... Yes there is Canned Ham. The ends of the pivot tubes do indeed seat against the frame tabs, but if you crank those bolts down so tight that you deform the tabs, they can pinch against the end of the bushing causing the a arm tube to start rotating on the outer surface of the bushing rather than the bushing rotating on the pivot shaft and against the tab surface as designed. There's no grease on that outer bushing surface and with water, sand and mud acting as an abrasive the a arm tube will wear very quickly requiring replacement. With Polaris suspension components, tighter is not better.

Oh, so you already have them cranked up all the way?

they were all the way up when I bought it over a year ago. I bought it used and finally have the space and money to really work on it and give it the love she deserves.

It can't deform the tabs unless it actually indents the bushing rod into the frame tab. It can't pull the frame tabs around the bushing rod. The bolt flanges are flat. I have installed 1000s of Polaris bushings and never had an issue with over-torqing them no matter how much I tighten and especially never seen the bushing spin in the a arm.

Ok. I guess if it works for you, tighten them as tight as you want. I'll continue to do 37 ft.lb.

so my service manual does say 45ft.lb. I noticed though that in doing so the a-arms take a lot of effort to move up and down. I dropped it to 40 and that helped a lot. Im not a fan of tightening the crap out of a bolt, that causea things to stress br

Installed the cecco frame braces and love them. The rear was a pain to put on. Between the 5lbs of coal and rock on the top of my skid plates and the rear brake line always in the way, it was a good time.

Excited to be heading to HMT this thursday!

And see if you had done the Ball Bearings in your A arms it would be no binding and would ride so much better.
