85.5 944 re-instal CV axles, any tips?

[Yuta]

Hello guys,

I am planning to re-install the CV axels that has been sitting insdie my car for 3 years.. Before I do it, I have a few questions:

1. Looks like the left and right are the same, is it correct?

2. The hub to the wheel and the hub to the differential are the same? You can put on either way?

3. Do I have to repack grease? Wipe off the old grease and put new grease in? What kind of grease you recommand? I have a Valvoline multi-purpose grease handy, the color is red, can I use it? Or I have to buy something special?

Thanks in advance

You should disassemble, clean and inspect. Reassemble with new boots and grease from this kit (4 needed):

Its not worth doing unless you fully dissassemble, degrease, clean, regrease and install with new boots. Whole project should be ~$75. I would also recommend taking a wire wheel to the axles and repainting them.

REMEMBER that the CV joints themselves can be assembled completely wrong- its easy to do but if you have the inner race spun 90deg it will go together but not twist as it should. If you dont pay attention you wont realize your mistake until you try to install them and realize the wont fit in place like that. Easier than it sounds though

Thanks guys! I am wondering if it would be difficult for me to put on cv axles after muffler is installed. Looks like it is much easier to install cv axles, especially the right one, when the muffler is not there..

Its slightly easier but its no deal-breaker, I dont bother with it unless the whole transmission is coming. I drape a rag over it though otherwise grease is going on it for sure.

Also strongly recommend new fasteners.

There are some other old ones with black beauty if you have been around a while. These pictures are more specific to the 44 series not the 108s used on the 930s, ect

And this picture is good. Like Bruce Anderson, Grady Clay was an asset to the community.

Acetone cleaned mating surfaces and clean mounting threads are important as well as the fasteners.

Like the belts and lug nuts, re check the torque after a tank or so. I went with 33 ft pounds with a thread protruding. The gnk supplied bolts where too short for my application. Buying new ones is about 1/3 the mess))

Yes, make sure the mating surfaces are completely clean of any grease! It's the friction between the two surfaces that transmit the torque across. The bolts are only to clamp them together to increase friction. Bolts cannot be loaded in shear! Any grease and/or insufficient torque on the bolts will allow some slippage and.... >SNAP<
