108 Grease Points - PeachParts Mercedes-Benz Forum

zambo · #1 11-29-2003, 08:15 AM

I had my '72 3.5 up on the hoist today and put a bit of grease into the king pin grease nipples but remembered hearing that there are many grease nipple points on the car.

Does anyone have a diagram/chart in jpeg form that they could send me that shows where all the points are?

Any help gratefully received.

Thanks

Richard

If I had an owners manual for my 4.5, I'd point them all out to you.
The best I can do is tell you whats on my 220S.
Front axle (upper and lower wishbones 8)
steering knuckles 6
intermediate steering lever 1
driveshaft 1
rear axle suspension 2

They're kind of similar. Hope that gives you some help.

Frequency states every 1,900 miles. I try to get em at each oil change. It's okay to have the grease overflowing out of the seams.

Don't have a diagram handy, but here's the scoop:

I think you got the steering knuckle points -- one on the front on the right side, one on the back on the left (I think, being dyxlexic, right and left are hard sometimes....). Top kingpin trunion is a right angle fitting straight up from the steering knuckle fitting, points back on both sides as I remember.

Lower trunion is at the bottom of the kingpin, deep in the "hole" at the end of the lower control arm. You will probably have to dig out all the old grease and dirt to find it.

There is a fitting on the ends of the inside of the control arms, upper and lower. One set is straight out (the uppers, I think), the other set is underneath, sorta hidden. Dig around in the old grease, it will show up.

U-joint fittingis burried in there, you will have to rotate the driveshaft until you see it close to the center of the cross (I think).

The rear ones are for the bushing for the axle pivot, and one of them requires that the axles be hanging to get to it -- that means put jack stands under the jack points.

Hope this helps!

Assuming the w111 is more or less the same, I found some but not all of the grease points. The driveshaft didn't appear to have any in the vicinity of the U-joints (middle or rear) but did have one up by the rubber donut. I greased it but couldn't see where the grease should come out, perhaps it was blocked by the donut. Also, why would a rubber donut need grease? Is it going some other hidden place?

The two at the rear axle pivot were simple, as were the 4 on the inside upper control arms. I could not find the 4 for the inside lower control arms, mine just has flat caps on the ends.

I found 1 more (per side) on the top of the kingpin AIMED IN towards the shock, in a horribly inconvenient place. I suppose I have to remove the front wheels to get to it in any kind of civilized manner. Regardless, it seems like my grease gun's fitting won't fit in that tiny space. It's pretty low profile with a long hose so I can't understand how to grease it without removing the shock/etc. There must be a way.

So 8 grease fittings seem to be hiding, the 4 on the inside lower control arms and the remaining 4 for the bottom of the kingpin? My car doesn't seem to have any on the door hinges that I can see, then again they don't squeak anyway.

Perhaps 108's have 2 per side at the top of the kingpin, and 111's just have that 1 facing in?

Wow, that thanx vox! The w111.net link illustrates everything very nicely! I never thought to look on the SIDE of the kingpin or on the inside shaft of the control arms, that's where they're hiding. And thanx arthur for the driveshaft info. Any clues on the top kingpin fitting, how did you all fit your grease guns on there? Perhaps my fitting just got twisted, it's pointing in towards the engine.

The grease fitting is an angle fitting..you simply put a wrench on it and face it any way you want for easier access................

Bingo! thanks again, I should've figured this out, haha.

Basicaly, anywhere there is a hinge joint there is a grease nipple. I use Mobil 1 synthetic grease. The big problem is that the FS is not greased so the upper outer adjustment welds itself together through friction. Then the adjuster bolt needs to be torched to get it apart and the kingpin replaced.

If you have trouble getting grease into the nipple, use a heat gun on the area and the old grease will liquify and the new grease will go right in.

Zambo, beyond hunt'n peck gotta reconnoitre 3 topside and 2 bottomside on yer kingpins and one halfway down...... also amidships at driveshaft (+ one at each universal joint on older cars) and one on rear swingarm knuckle at the pumpkin. More existed on earlier kingpin susp 111's at steering rack ball joints too.

Owner's manual to VMB's is worth special ordering. It covers pict schematics yer looking for, also tech tuneup info like valve clearances, maintenance schedules, etc. Even more critical is the parts schematic catalogue book issued with the car - considered the 'holy bible' as practically all ye need to disassemble and replace anything on the car.

Finally finished the greasing today, removing the front wheels made it a piece of cake to find/reach everything and this is the route I'll be going in the future. It took far longer for me to do this than to adjust the valves, mostly due to the time to properly raise and secure the car in my cramped garage space. Ah well, at least I have garage space...
