Hi, get there anyone experience with changing the seal in the rear axle differential?

The number in the part list is 12.

Thanks for your answer.

Max.

 

this is not a warrantee covered part?

if it's where the axle slides out, then it will be an easy repair, but the front bearing seal will not go as smoothly.

i just saw part number 12, that is the front seal, damn that's gonna be a tough one, well undo the nut and pull that CV joint adapter off, and you might have access to the seal from there. just pry it out and reinstall.

 

Max, sure you want to do it on your own? It looks like the seal is inside the housing. Your mechanics unable to fix it?
I wouldn't touch the darn thing. How about special tools? Shaft seals installation? Balancing the shaft?
No warranty anymore?

Greets,

The problem is that i get a new differntial last march 2006 and my warrant is off in May 2006. Now my DC Dealer says that he can´t replace the differential on himself cost´s. No warranty no repair no obligingness!!!

To moved the seal isn´t a big deal but i need a special tool to measure the friction torque.

Any idea where i get this tool?

Max.

 

Have you asked your dealer? Maybe you try a MB-Shop too. Quite possible the numbering is not the same, but explaining them what you need and showing the pictures should be info enough.

 

That doesn't look like a special tool to me, looks more like a torque wrench, ay?

You can order the seal install tool but usually I get away with a small ballpeen hammer and carefully tap it into the housing squarely.

 

There isn't a torque wrench !

I get today a answer and that what i need is a friction gauge from stahlwille. Indicating torque wrench with permanently attached square drive and trailing pointer dial. No needle wobble during measurements. Lightweight construction through use of aluminum and cost over $500 !!!

Sounds pretty wild!!! Oh I'm so lucky my XF is still on warranty.
I'll get a new differential next monday. Including the bearing in the center. Well I hope about the bearing. Had to make a phone call to DC to ensure that my mech is permitted to change it.

Max, what will you do?

 

What's the friction gauge for? It looks more like a glorified Newton scale, probably used for measuring drag on the pinion gear or crush washer???

 

Why you need the friction gauge listen in point 5 of repair manual (attached)!

chxf,

the next step is that i order the tool and will shipping next week. the seal and the center bearing i order by DC. i get from a DC mechanic the bearing number. i get a special oil from DC to fill in the differential. is much better than usually the mechanic's fill in!! Is from castrol and call SAF-XJ, a fully synthetic final drive lubricant. SAE75W-140, API GL5

 

The friction gauge [or better known here in the U.S. as a torque wrench] is for setting the pinion bearings preload, if this is not set at the correct friction [or drag] you could damage your pinion bearings and possibly your pinion and ring gear, that is in the rear differential . Save your self a lot of time and possibly money and leave it to the professional.

 

If your going to all this trouble, tear that diff out and get a posi unit from Quaife. http://www.quaifeamerica.com/differe.../diff_apps.htm
It's not cheap $1,700 but since your gonna be ***** deep, might as well go all the way.
Personally I would install the SRT6 gears in my 6 speed car, just to make 1st gear a little more useable for the street, then later on you can change the tire and rim diameter to something that is a little less expensive for Lo-pro tires.

 

Older thread, but Quaife offers a LSD for the crossfire? can you show me the source of where you came by this information or where I can purchase this product? As far as I know they were NEVER offered for crossfire or slk.. a single slk owner even went through the hassle of purchasing one from Kleemann Europe for a cost of $4,000.. If one was offered for our cars at $1,700 I would be all over that...

I sure hope you are right...
