Front Subframe Repair!

Posted on

The car is off to Ken at Vintage BMW Racing for the front subframe swap. The trip for the car to get there was NOT uneventful. Called AAA for a tow truck and when they arrived they refused to tow the car. Claimed it was against the AAA rules to tow a modified car. I explained that it had been towed before without a problem. Nope the tow truck driver refused. So I called AAA again and 2 hours later another truck shows up and this guy gets the car on the flatbed in minutes.

Ken got the old subframe off, the new one painted and everything reinstalled with new hardware and a new idler arm bushing.

The process is pretty straightforward, just labor intensive.  You suspend the engine from above.  Then you unbolt the suspension, steering box and unbolt the subframe.  Then put the new subframe on and reverse the process.  I already had new poly bushings on the car so the suspension was very tight.  The idler arm bushings were stock as the subframe has never been removed from the car.  So a new idler arm bushing will complete the suspension rehab.

The car is back on the road and feels amazing! The steering was starting to get a little sloppy but now the word I would use is telepathic. If you think about lane changes or steering inputs the car just does it.  Not sure if its a function of the engine kinda moving around, the idler arm bushing, the fact that everything got removed and put back together or a little bit of everything.  Bottom line is the car is better off than it was before this failure which is how I have built the car up to now.  Whenever something fails, fix it with something better than the original.
