I'd like to know this too. Local shop quoted me approximately 2hrs per bushing to remove and reinstall the bushings. Also told me that the bushings can't be removed while on the vehicle and that a special tool is required. If that is the case I can't see that replacing the bushings is cost effective. I may just swap the trailing arms and move on.

It depends on the amount of pressure required to press them out, some bushings you just can't do by hand while underneath a car. The redneck and extremely risky way to do it is by cutting the bushing.

I understand that, but what is a reasonable expectation as to the time and cost to remove and reinstall the bushings.

Sorry for the delay guys I wanted to find some of our old pictures for yall. The design of the factory control arm causes it to flex under heavy load (hard driving, tracking, etc) instead of at the bushing locations. This flexing of the arm causes the metal to fatigue from flexing (metal doesn't like flex back and forth) and eventually the arms fail under normal driving conditions.
After having our company cars arms tweak to the point that when they were installed on the car you could visually see the two arms were twisted in an unintended fashion, we removed them for replacement. Once removed it was noted they had become torqued during driving to the point they stayed in the bent position after being removed. Dealing with trailing arm failure ourselves and noting a multitude of failures of customer arms, we tasked our R&D engineers with coming up with a better trailing arm. Our arms are designed to eliminate twisting problem the factory arm has, being lighter than the factory arms is an added bonus. Our design takes the flexing under heavy load out of the trailing arms, and places it on the bushings were it belongs. -James |

In the case of your company cars, did you find the permanent bending of the arms occurred when using the soft stock rubber bushes? Or were you using an aftermarket bushing? |

Moreover, should we upgrade the control arm and a group m bushings from turner motorsports, or only bushings or only trail arms?

As many 135, 335i, 1M and M3's we work on and prepare for both sport street and weekend track duty we have yet to see one with a bent trailing link. Even cars with solid subframe bushings(Turner) and spherical bearings(Bimmerworld, Turner and TCKR) in the suspension pickup points. |

Holesaw the bushing center out, then sawzall through the casing until it pops. Once the tension is off you can push it out by hand. Takes 2 minutes per bushing. Works for the diff bushings too.

Installed my ECS Tuning rear trailing arms. They are definitely lighter and more rigid than the OEM trailing arms. My OEM trailing arms don't show any visible signs of distortion or fatigue. I decided not to install the Whiteline poly bushings at this time. I'll save them for later.

Nice, any more reviews/impressions?
M bits dont impact this part unless you have M3/1m Knucles, even then it should be fine

rear trailing arms
HM Motorsports has never seen a "bent" rear trailing arm on any car. My mechanic suggested spending the $ on more vital components. He just replaced all of my front and rear, Upper and Lower control arms with the M variety, and upgraded my Sub-frame bushings too. The final piece of the puzzle were Megan rear Toe-control arms. This helped to set the correct camber and toe because the M parts are wider and longer. Needed another Alignment of course.
The car now handles better than ever!

I hate to bring back such an old thread, but has anyone else who added the ECS rear trailing arms also changed the bushings? If so, what bushings did you use? And how much did it cost to have the bushing replaced?
I still haven't replaced my bushings.
