Need help with rear subframe bushing replacement

[bmwm42]

If all that you want to do is replace the rear subframe bushings, then the tool is the way to go. If you want to replace the subframe bushings, RTABs and brake lines, it makes more sense to just drop the subframe. And if you are dropping the subframe anyway, the tool is more effort than properly applied fire.

Takes no more then 5 mins with the tool to remove the bushings with or without the subframe removed...I don't like wasting time on shit if I dont need to...and if you're going to replace the rtab you still dont need to remove the subframe. ..its stupid and unnecessary to remove the diff for this job unless your changing out the bushing for it.

I rented the tool from someone on r3v to do mine. It took me one hour start to finish to do both sides. People talk about this job like it is a nightmare, but a lot of people don't use the tool and create a lot of work for themselves in the process.

Question: could you slice up a full pizza without a pizza roller? Yes. Would it be a lot easier with a pizza roller, of course. RSFB replacement can follow the same logic.

Lies doesnt take all day this takes an hr tops with the tool....there isnt a need to remove the subframe unless your welding in camber caster plates etc

If you are *just* replacing the subframe bushings, then it makes sense to use the tool and do it on the car.

If you intend to do more (like the trailing arm bushings), it makes more sense to pull the subframe.

The hardest part is actually getting the subframe separated from the chassis.

$800 is not a bad quote for that kind of work, it does take all day.

Sometimes this works. This is what I did. Didn't exactly come right out. Ended up getting a steel chisel and split it in half.

You didn't use enough heat, then. :p MAPP at least. Forget propane.

I have the bmw subframe bushing tool/rtab tool for rent if needed

Rent this, it'll save you a major head ache and you don't need to pull the subframe to do it.

Heat the subframe instead. Once you melt the rubber on the outside of the bushing's metal ring, it'll slide right out. And with FAR less nauseating black smoke.

Ya need a blow torch
And then a hack saw to cut out the metal ring
Connect the blade through the center n cut
Use a hammer n screw driver once fully cut
Don't score the subframe with the saw
Press in new bushings and re install

I just removed my rear subframe & took it to a suspension shop. $50 later, they pressed out the old bushes and put in the new ones.

Tie your rearend to a tree and drive really fast. It will pop out in no time at all.

Is that how you got your front subframe out? You don't get to work on my car.

What else should I replace while I have the subframe out? Trailing arm bushings?

Diff mount, sway bar bushings and end links, brake lines. Tons to do back tgere

To change the bushings yes, but it will take a couple hours to remove and install the subframe.

love your car!
