Like the way the video was made after the spring was fitted

[@pmcgrorty]

I'm not a youtuber and simply posted to help others as there was very little info. on KZbin about them. ;)

[@SirCharlesthe20th]

Just had my rear springs break... just as you explained

[@andydonaldson5593]

Really useful. Where do you jack the rear end up?

[@MrGrzegorz22crewe]

Thank you for sharing this knowledge🍺👍🍺

[@brendonbaker764]

Any particular size shims to use? My 2012 E350 has the sporty package so I’m not sure which size shims to use.

[@tommykopperud4638]

I have to do that job on mine. Was thinking about removing the inner bolt instead. Will that be a solution?

[@grindergrip]

No. You have to remove the outter bots . Just losen the inner bots so the arm can move up and down. After putting the spring in correctly at the top, I used the jack to lift the lower arm which helped compress the spring and allowed me to put the shock, drop link and hub nuts and bots back on

[@RothBeyondTheGrave]

​@@grindergrip in case anyone reads this 2 yrs after, this is incorrect. You can confirm with any Mercedes specialist, master tech, or foreman as I have. The inner bolt is removed along with shock & end link bolts. Arm then is gently lowered, spring removed, & reinstalled.

[@barrykehoe996]

Any particular reason not to use spring compressors? I have a set that you clamp down on opposite sides of the spring and then tighten them down. Would these not work??

[@pmcgrorty]

Pretty sure from memory the WIS (Mercedes Work Instruction) actually uses the compressor but it's a telescopic style. Not the little threaded rod style compressors that are prone to snapping. ;) These springs are pretty solid and I wouldn't want to try the little ones on them. I use a telescopic one to compress the new spring and get the angle correct for seating the spring when putting this back in.

[@jmreire1]

The bolt nearest to the axle / brake which holds the bottom arm in place, is that just a straight through bolt, or does it have an offset? Ditto the inn er bolt? Thanks

[@pmcgrorty]

Just standard bolts/nuts.

[@NateEll]

I just learned that I too have a broken spring. Is a rear alignment needed after spring replacement?

[@pmcgrorty]

No need for alignment

[@boigoe]

Hi just wanted to know wat size are the upper rubber shims? Thanks

[@pmcgrorty]

Just order from dealer.

[@boigoe]

I had these springs changed on my w212 2009 with the same springs 40404 number and the rear is super high...mine is a sport model...its a dealer part and like I said the rear is high...did u have same problem or was the rear perfect height? Thanks

[@pmcgrorty]

No problem. Matched springs from Mwrcedes parts to those fitted (colour coded) and all was well. Important to double check the spring part number then check again as dealers been known to make a mistake.

[@boigoe]

@@pmcgrorty colour code is correct but the back is well high...dealers don't know wat they doin...guess il have to live with a e250cdi that looks like a monster truck from the rear

[@pmcgrorty]

@@boigoe I wouldn't live with it. If spring is correct can only be shim, spring top mount or rubber bush or incorrect assembly. Tell them to do the job again.

[@grindergrip]

Is there a way of putting the spring back on without having to compress it?

[@pmcgrorty]

Very difficult and not recommended. I wouldn't try it.

[@grindergrip]

I had to replace mine a few months ago after watching this video. I didn't have a Spring compressor so I had to use a trolly jack. It worked perfectly fine as I used it to push from the bottom which caused the spring to compress and allow me to put the nuts and bots back on.

[@deth5619]

@@grindergrip That sounds dangerous as shit

[@grindergrip]

@@deth5619 you got to live on the edge sometimes 😂. Had to make do with what I had at the time and the spring would not go anywhere as it was obstructed by other components so wouldn't really fly out 🙏🏽

[@brendonbaker764]

Any particular size shims to use? My 2012 E350 has the sporty package so I’m not sure which size shims to use.

[@pmcgrorty]

Just ask the dealer. They sell them along with the springs.
