Re: [MBZ] Seeking Flex Disk Advice
On a car that is in excess of 30 years old, you can almost bet that a lot of the undercarriage rubber bits are original or weren't changed in recent history. Now granted, my knowledge is a bit dated, but the cost of the parts involved isn't significant, nor is their replacement. Putting new pieces in will make a big difference in how the car sounds, rides and runs, without exception. Some parts, such as the differential mount, can even have a major effect on the handling and ultimately the safety of the car under certain conditions. Here are some parts prices from the "Q" based on a 1983 300SD (W126): Motor mount - $26/ea for Lemforders (the best) Transmission mount - $23 Differential mount - $75 OK, so there is about $150 for these parts. Amortize that over the life of the car, even for the miles only you have put on it, and it's cheap. And I can assure you that if these pieces are even half worn, you'll still see a noticeable improvement in the car in a number of areas. And I'm not being obsessive about this - it just makes sense to do it if you're going to be in the neighborhood, so to speak.

Re: [MBZ] Seeking Flex Disk Advice
Mike, Crawling under the car highlights all the over engineering that allows our cars to run like tops. Sadly, there is a bunch of shoe horning going on and you end up taking all sort of things off and then replace the wear items so you can do the job right. I learned about the flex disk/motor mount relationship at our local section tech session this weekend. I had never thought about the motor and transmission angle change/drop impacting the driveshaft angles and creating more trouble for the disk. Makes sense though. Taking the whole car apart was another item, since three of the cars on the rack had disk issues. Gump was stone simple and doing a disk swap was not a problem. Wide open and nothing in the way. Froggy has the dang exhaust impinging on the driveshaft, the newer cars have all sorts of pipes, tubes, hoses and stuff routed all over. To get into the drive shaft, you have to take the underside of the car apart. Might as well hit the wear items while you have it open instead of paying for it down the road. Labor is done now, just parts. Next time labor cost gets tossed in. The water pump in Frosch is weeping. Stealer quotes $2500 for the job. Indy wants $900. I might be able to find time on BiL shop schedule to cut that by a goodly amount. I already paid indy to swap in a thermostat. Should have done the dang pump then, replaced the old hoses and tossed on new belts. One of the "while you are in there" solutions. clay 1974 450sl - Frosch - Two tone green 1972 220D - Gump - She is green, simple and ran 1995 E300D - Cleo - Used by the Queen of Denial POS 1987 SDL - Beware Nigerian Scammers On Mar 4, 2013, at 7:01 AM, Michael Canfield wrote: > I understand that.

Re: [MBZ] Seeking Flex Disk Advice
Only if you are going to replace the cv axles and seals, wheel bearings and seals, shock absorbers, all rubber suspension bushings, windshield wipers and seat springs at the same time. All, just because they are not new? I can understand if they are needing replacement that it should be done at the most convenient time but the logic that goes with replacing parts just because you don't know how long they have been there is going to get costly in a hurry.

Re: [MBZ] Seeking Flex Disk Advice
My point was that if you go to the trouble to get the car up on ramps or lifts or stands or whatever, and you are nasty and crawling around under there, and if that other stuff has not been tended to in some time, then take advantage of the situation and deal with it. Or not. Your choice. --R (whose curmudgeon has not been sequestered) On 3/4/13 10:01 AM, Michael Canfield wrote: But, we started out @ flex discs and ended up with a laundry list of parts from the oil in the rear diff to the exhaust hangers all the way up to the motor mounts.

Re: [MBZ] Seeking Flex Disk Advice
It depends on when the motor mounts were last replaced, if you know. This is really delayed maintenance, as most are driven till they fail, rether than being replaced when they should be. If you can find a used MB that has been properly maintained, it can be a "cheap Mercedes". If you buy one that has been run into the ground at a "bargain price", and you want it to be "up to snuff", you will find that "there is no such thing as a cheap Mercedes". If you are willing to just keep it running without worrying about everything being correct and are willing to endure occasional break downs, then yes, you can have a cheap Mercedes. You make your choices and pay the prices - TANSTAAFL. The same thing applies to old Cessnas (don't ask how I know), but the consequences of an "occasional breakdown" are significantly different!

Re: [MBZ] Seeking Flex Disk Advice
As I recall, only dropping the exhaust is necessary, even if you're doing the center support. Also, you should not bolt the center support down tight until the car is on the ground and the suspension is loaded, which can be a bit tricky to do. The nuts that come with the flex disk are self locking, and do not require thread locking compound. The last portion of the threads are altered slightly to create and interference fit, which prevents the nuts from coming loose. This is also the biggest hindrance to removing the old one, and why you will need a 1/2" breaker bar to get them loose. While I suspect my car might have benefitted from a new center bearing and carrier (these are pretty inexpensive in the grand scheme of things) when I did my flex discs, gaining access to the center bearing and carrier on the W140 is a major undertaking, requiring dropping of the exhaust and many, many heat shields and such Dan On Mar 3, 2013, at 3:47 PM, Michael Canfield wrote: > Simply raising one rear wheel off your block a bit with the factory jack > will allow you to rotate the driveshaft to a position where the bolts are > easy to get to.

Re: [MBZ] Seeking Flex Disk Advice
Simply raising one rear wheel off your block a bit with the factory jack will allow you to rotate the driveshaft to a position where the bolts are easy to get to. Lower it back down to hold it still. Don't mess with the exhaust bolts if they look rusty. Simply support it, remove the rubber hangers and lower it out of the way. It will flex enough to make room. Broken bolts suck.

Re: [MBZ] Seeking Flex Disk Advice
There is a small cross member that holds the carrier bearing, which you have to take down to do the rear flex disk anyway, else the shaft won't move enough to get it off the flex disk. When you put it back together, be careful not to get the clamp nut too tight -- reef down on it and it will cause the shaft to vibrate, it has to move very sightly to allow the differences in length due to the u-joint. Will sound and feel like a bad muffler if you get it too tight.

Re: [MBZ] Seeking Flex Disk Advice
Yes. Mark BOTH halves of the drive shaft with WHITE, or another light (easily identified) color BEFORE you separate them. The cross member you speak of holds the tranny and tranny mount, it can stay in place to do the d/s bearing.

Re: [MBZ] Seeking Flex Disk Advice
Make sure to use jack stands and not ramps. You will need to turn the driveshaft, and that's a tiny bit challenging when on ramps :) Plan to use a BFH (big hammer) to loosen the old flex disk from the drive shaft, it will be stubborn.

Re: [MBZ] Seeking Flex Disk Advice
Pretty straightforward on the W126. Get the car up in the air, have some 19mm wrenches handy, and go to it. You might have to loosen the big nut on the drive shaft, but in most cases there is enough slop in the drive train you can push things apart with a pry bar. A cheap plumber's basin wrench will do the job on the clamping but if you do need to loosen it. You will have to separate the joints far enough to get the drive shaft off of the pin that's in the middle of the yoke. Also be sure you grease up the bushing that fits over the pin before you reassemble. Dropping the rear of the transmission, such as you might to change the transmission mount, makes it a little easier, but you'll need a jack to support the back of the transmission if you do. DO NOT drop the drive shaft. It's not necessary and you risk not getting it back together properly unless you mark it before removal. Lots of grunt work, but not a terribly difficult job. Also, don't buy the cheap Chinese flex discs. Dan On Mar 2, 2013, at 7:06 PM, Scott and Gwen Ritchey wrote: > I need to replace the flex disks on my 1982 300 SD.

[MBZ] Seeking Flex Disk Advice
I need to replace the flex disks on my 1982 300 SD. As far as I know, the old ones are original. I haven't done this job on a 126 chassis so I'm looking for any advice before I call Rusty and start wrenching. Thanks in advance for any insight.
