I am planning to replace the engine and transmission mounts on my 540. Any brand perference? Anyone know what brand BMW uses? I see Boge/Sachs, Lemfoerder, Meyle and Corteco offerred. I am kind of thinking Boge/Sachs is probably oem.

Thanks!

I'm guessing you'll get a lot of shout outs for Lemfoerder because they typically make the best suspension wear items, but boge/sachs would probably be fine too.

Let me know if you want a hand doing this, I'm going to do mine at some point too and having a trial run can't hurt.

My current project du jour is working with the UUC black transmission mounts. So far I have vibration problems right at 2K RPM but UUC is quite specific that I shouldn't have vibration or there is a problem. In re-tracing my steps I think I goofed and pre-loaded the bushings so I'm gonna lift the transmission again this week and re-do it. If the vibration doesn't go away then I'll go back to OEM.

Bottom line though - new mounts feel fantastic! At 83K for me there was a lot of slushy movement in the drive train and new trans mounts cured it. The ones that came out were pretty squishy.

Well if no other input, I am planning to order the Boge/Sachs brand engine mounts, and Lemforder trans mounts, as that this the combo one online seller offers. Many sellers offer the Corteco (including our sponsors) which is an aftermarket brand from Europe and the Meyle are about $10 to $15 less expensive that all the others...but I really want to stick with oem for these critical parts, and not induce unwanted noise or vibration.

Thanks!

Autopartswarehouse.com carries both the Sachs/Boge engine mounts and Lemforder automatic transmission mounts for the 540. $150 for all of them, with free shipping, a pretty good deal. They are a mixed bag on BMW parts, not carrying the more desirable brands in many cases, but it worked out for these mounts. ;) And I lucked out that these were in stock in a local warehouse near Seattle, so I got them the next day after they shipped...about two days total from day of ordering.

Update: I received my Boge/Sachs engine mounts and when I opened the boxeds, they have "Corteco" stickers on them! So apparently Corteco is either part of Boge/Sachs or they are buying them from them....couldn't have been a swap at the retailer, as they were factory sealed boxes they came in. So you are rest assurred the Corteco are oem, as they were identical in all markings to the ones removed.

Oh, and the swap went very quickly, as my buddy has a well equipped home garage with lifts. We used his two post for this job and had the engine and trans mounts swapped in 40 minutes. At 125k miles the left side engine mount had only the slightest horizontal crack developing, and the right side was fine. Neither showed signs of compressing. The trans mounts were just starting to seperate on the top portion from the metal threaded end.

So I could have gone longer, but probably still a good idea to have changed them.

Actually corteco is oem for the engine mounts, If you order the boge/sachs there is a 99.9% chance there will be a corteco sticker on them.

Edit, Should have read the entire posts, Just read the first few.

OEM is best to be sure that you do not pick up some vibration or harmonics.

The OEM units have been tuned for the car. Aftermarket brands are not are tuned.

Aftermarket units will not add 25 mph to your top speed nor allow you to pull 3 Gs in a turn.

I'd like to introduce you to my local dealer
Well, my buddy works "off the clock" and only charges straight time, not "book time" so if he does it in one hour then it is $75, cash under the table, versus the $95 or $105 the dealer charges, plus shop fee and tax....plus the "book time" for engine mounts alone is probably 1.5 hours, and then another .5 hours for the transmission mounts.

Ended up he was busy, so another friend helped me....he has the most well equipped personal shop you have ever seen, with many specialised tools. We knocked it out in just under 40 minutes from start to finish! And he did it for nothing....okay, I owe him dinner. ;)

Mounts can be done in a very short time if you have the equipment like a dealer. Even at home on the driveway they are a quick fix.

A dealer could swap in new ones in 15 to 20 minutes.

I could perceive little to no difference...though it felt smoother, that may be just because I am looking for an improvement.

Agreed, we did both engine and transmission mounts, from starting onto the 2-post lift to off in 40 minutes. Engine mounts were easily done in 20 minutes. Could have been faster, but reaching the top of the driver side mount requires a bunch of extensions to reach...that is simple enough for removal, but getting the nut back on from above was a pain....we used some sticky wheel bearing grease to hold the nut to the socket...still took four tries, but we got it. :) Right side can all be done from below, IF you have the right tools.

The trick tool my buddy had was this tall tripod looking thing...resembled a 5 foot high jack stand...but it had a long threaded steel pole in the center, with a 3" square pad. Once we loosened both engine mounts, we slipped that under the engine, right next to and above the mount, and lifted the engine up a few inches. Slipped out the mount, and slid in the new. Then did the other side, and replaced all the nuts and tightened back up. It was pretty slick, and much easier than using a jack, and a 4x4 post and plywood under the oil pan to lift the engine. ;)

He also has four tall rolling tool cases full of SnapOn tools, so we had every angled ratchet, wrench and tool needed for reaching some of the hard to get at nuts.
