i only cross threaded a small section of the threads, 3/4th's were still good, he retapped with original threaded tap, and the bolts went in with no problems, red locktite was used aswell.

I just installed these last weekend. If you are trying to get the rears back in, loosen the front subframe bolts - this will give some slack. If you just take the rears out and drop it enough to get the upper bushings in, the bolts will only hand-thread in a few turns then stop. If this happens, do not get a wrench to apply more torque! Loosen the front bolts and play with the height of the rear or shift it around a bit as you hand tighten the bolt. You should be able to hand tighten it most of the way.

Wish I read this before I started my install, Fucked both sides up. Not too bad but enough to be stuck without the tap. Lead time for a long 14 1.5 is about three weeks. Went to 6 different stores today with no luck, only 14x 1.25.

Good thing I have another car. The Whiteline instructions should tell you that it might be a good idea to loosen the front mounts to get a better angle on the rear bolts.

Well I'm one of the guys who messed up my passenger rear subframe mount, that was mentioned in a previous thread. My tap is on its way to @Brinks . I said I would make it a community tap for anyone needing it, so if you need one in the near future... contact Anthony @Brinks).

wow, red loctite? You wont be taking those off again haha.

Glad its all fixed though, and a good thread as a heads up to people installing bushings.

Someone 10-15 years from now who gets the car and wants to take those out will want to strangle him (I think we all know that feeling when dealing with used cars).

haha, right? I picked up a motorcycle a few months back, and the previous owner(s) did some "interesting" things.

I sometimes wonder if/when I sell my car, if the next person will be like "wtf did this guy do"

Just got everything dialed in. The threads were not messed up too bad. loosened up the front mounts to align the rear and hand tighten the bolts till they came flush with the sub frame. Its kinda obvious in retrospect that you need to loosen the fronts before threading the rears.

To anybody that is thinking about this install, make sure you look up through the sub-frame mounts to see if everything is aligned first before you even start to thread the bolt. If the bolts stops by hand, take it out and preposition the subframe.

Thanks again @Kwaziekeller
If anybody needs a long 14x1.5 Tap hit me up,,.

Probably not a good idea to use red lock tight either, you have to use a torch to loosen that stuff up.

Kwaziekeller · 07-31-2014, 12:00 PM

No problem, glad u got everything fixed and the car back on the road. I figured that I only bought the tap for that purpose so why not share it around since I probably won't need it ever again.

Brinks · 07-31-2014, 04:34 PM

Anybody have to have the rear alignment done after installing? I'm getting some vibration through the gas pedal.

Edit - ended up being an exhaust leak

Had this happen to me... wish I had found this thread earlier... friend lent me a tap and die set with the 14x1.5 set, and now have the rear of my subframe on...

Still gonna order a 14x1.5 helicoil set just in case something happens down the road...
