    MAPerformance Trailing Arm Install Guide

    Torque specs for re-installation on the way. Maybe you can help out Darkman?






















    If you have any questions please let me know!

    Please note that I still don't have a widened factory wheel to get the biggest tire you can install with our arms. The issue at hand is that this product/project is totally funded out of my personal wallet as far as wheels/tires go. After purchasing a set of coilovers I was not ready for because of a manufacturer issue (Story, another day) funding is quite low.

    I am also working on a lot of other products that are getting funded by my personal wallet, so please be patient. The big tire debacle will be solved soon once I find a company to widen my factory wheels in a decent amount of time.

    Goal is to fit 315's without a spacer on a 10.5" factory widened wheel, which with all the measuring I have done shouldn't be a problem. Again, I will get the answer soon, so please don't clutter this install thread with questions concerning that subject. Please use the other thread to do so!

    -Adam

    Re: MAPerformance Trailing Arm Install Guide

    I was taught that suspension bushings should be tightened with the suspension loaded to prevent binding or pre-loading the bushings.

    I'd love to have 315's, but don't want to spend the money right now. Maybe next summer. What aspect ratio keeps the stock tire height with 315's?

    Trailing arm to frame is 66 lb ft.
    Front cradle bolts 195 lb ft.
    Trailing arm to knuckle mount 129 lb ft.

    Looks like the rear trailing arm bushing sleeve rotates in the bushing, so tightening it with a loaded suspension shouldn't be necessary. If the sleeve is vulcanized to the bushing, then yes you should.

    Nice, I just got my clutch and trailing arms today, very impressed by the quality of both. Definitely worth the wait.

    Thanks Tommy.

    BTW, the front cradle bushing does not need to be preloaded when installing either does the included hub bushing. Soflarick is correct when the sleeve rotates in the bushing, they are not mended together.

    What does it take to remove the factory bushing at the knuckle?

    so the front trl. arm that has the joint and spacer on top with the 6" bolt is 66lb ft. and the 2 bolts i took off to lower the cradle are 195 lb ft ? just want to be sure b/4 putting her back. thanks

    Re: MAPerformance Trailing Arm Install Guide

    The GM specs I found said 66 lb ft for the front trailing arm, the bolt and nut that go with the spacer. Tighten the nut, not the bolt, to get the proper torque on the fastener.

    I used a screwdriver and penetrating lubricant. Then put a screwdriver through the edge of the bushing and hammered it through to the other side and then started twisting.

    Another method is to burn the bushing out, or press the bushing out with a c-clamp and a small piece of tubing just bigger than the center sleeve.

    I found the screwdriver method to be the easiest, took me about 2-3 minutes to get each one out.

    thanks............and about the factory bushing, man that was a bear to get out....There has to be a better way, but i used a small drill bit being careful not to gouge the alum. barrel and made several holes[ in the ruber] and sprayed about a pint of WD-40 lol.....then nocked it out with a large punch and short arm heavy hammer. It worked.....I still have the drivers side to do, maybe someone has better way to make this easier.

    Re: MAPerformance Trailing Arm Install Guide

    The way I described above was pretty easy, screwdriver in one side. Pry it a little and spray penetrating fluid inside the hole that appears when you pry it. Spin it in a half moon direction, then repeat for the other side. Get it all lubed up, then put a screwdriver in the sleeve in the middle and pry it all the way to one side and use another screwdriver to coax it out the other side.

    Re: MAPerformance Trailing Arm Install Guide

    Why do you have to lower the cradle and take the rotor off? Is it because they are so thick or something?

    When I've taken my stock and bmr trailing arms on and off I just used a gear wrench (on bolthead side for lower end) and got em on/off just fine w/o removing any of that shit.

    Re: MAPerformance Trailing Arm Install Guide

    I never said lowering the cradle was to remove the rotor? Where did I say that at? It is to remove the front trailing arm bolt because the bolt is too long to come out the top if the cradle is not lowered in the front.

    I am also curious how you got the rear-most trailing arm bolt out without hitting the rotor? They are installed that way above in the picture from the factory. Which is dumb in my opinion.

    I didn't have to remove the rotor or anything when I did my BMR's either
