Default Am I the first to bust a trailing arm?

Map trailing arm, looks like it broke right at the weld clean off the knuckle bracket. Good times.


Had music blaring so I didn't hear it break or dragging, but could tell something was messing with my handling right away.

I'm assuming the maps give more clearance than the stock trailing arms? Those don't look as big and as rigid as the stock ones.

They are map trailing arms, which are supposed to be more solid than stockers, but I guess not. My rims are widened stockers.
And it was my passanger side also...

I still have a set of stockers off my car if you want them. Otherwise, go with Killernoodle's, if he'll make you some.

Thanks for the offer I still have my stock ones too, but they won't fit with my wheels anyway. It's a nice clean break at the weld so I'm just gonna reweld them.

the scrapping on the arm is from it dragging.
I have solid bushings on the rear knuckle maybe I'll swap them to some poly ones I have. Could have been a factor.

Also has anybody put the front trailing arm bolt in upside down with the nut on top? What a pain lowering the subframe just to get the trailing arms out.

Are MAP and Killernoodle trailing arms the only aftermarket options from the stock ones?

MAP doesn't make them anymore. Looks like I will be checking the welds on mine.

Killernoodle is not making any right now.

I cant remember maybe 225-250 for MAP plus you'll want a set of rear bushings, TIC makes some for like 75-100 or something. I'm not sure what killer noodle offers aside from bending/modding your stock arms?
Can't you find MAP's on ebay anymore?

Yep. I put them in upside down when I did my Killernoodle trailing arm installation, but it required removing a couple of threads on the end with a sawzall to ensure adequate clearance.

No indication of them backing out so far--it's been 2-3 months and I just tested the bolts last week. If you're paranoid, drop some blue threadlocker on them. I didn't.

Thanks man. I figured the bolt would need to be trimmed; good to know.
