    I just received the Porsche kit 928 332 924 02 from rockauto.com today. What tool/technique is used to attach the provided bands around the boot so as to get them tight?

    I use my wire cutters to squeeze the humped bit in. You could do it with regular pliers but the result isn't as good. Those are the good quality clips, I hate the cheap ones.

    A pic just for you :)

    Does anyone know where I can get just the bands? I bought the boot kits from Dennis McCann and I couldn't get those bands tight enough. I had the whole thing assembled and on the car when rotating the axle to get to the bolts the boots came off the joints. I tried zip strips but the one closest to the engine melted. I fabbed up a clamp but if I could get repacements I would.

    I am going to buy NAPA service tool part number 3191 (see pic) and the appropriate bands for this job. I'll talk to my local NAPA store to find out what the correct bands are and let you know.

    I think I found the correct torque settings for the bolts:

    My shop manual has an entry "securing axle-shaft to flanges" listed as 8 Nm/kgm. Using the following site:

    http://www.onlineconversion.com/torque.htm


    Conversion of 8 newton-meter to pound-foot yields 5.9 - way to low. Maybe you need to multiply by 10??


    I found this on a Mercedes Benz site:
    ------------------------------------------------
    Torque: Force x Moment Arm
    Several different torque conversion factors:
    1 mkg (kilogram-meter) =7.233 ft-lbs
    Ft-lbs x 1.355818 = Nm
    Nm x 7.375621211 = Ft-lb
    1 mkp (kilopond-meter) = 9.8 Nm
    ------------------------------------------------

    So 8 x 7.375621211 = 59 Ft-lb - seems like the correct number, right??

    With the awesome help of Tatcat (Rick from PCB...THANK YOU!!!!), we removed my CV joints, cleaned and repacked them and then attempted to use the bands that have the dimples with a little pull tab (not the ones pictured above). Simple to use, except a PITA to get tight. In fact, one band came off as we were installing the newly R&R'd shaft. I'm taking mine to a professional shop tomorrow to have them put on the good bands.

    Save your self conversion calculations in the future. Get a copy of the 328 Tech Specs & recalls from Steve Jenkens web site.

    It's torque table is very handy as it gives foot-lbs. It's relevant to any 3x8. In many cases, it gives the end point of Ferrari's constantly evolving torque specs for fasteners.

    "Securing axle shafts to flanges 8 Kg-m (57.5 ft-lbs)"

    & If you're replacing these nuts & bolts, the replacements must be grade 12.9.

    I have a special tool (made by K&D) for crimping those CV boot bands--too bad I didn't go deep into this post I could've loaned it to you when I sent the drill bit.
    BTW, the bit went today.

    Thanks for the bit! I'm not going to use the bands that came with the kit - I bought the tool and bands from NAPA.

    Whats the NAPA part number on the bands? I want to replace the ones I got with my boots.

    I bought one set from a Ferrari part shop, I just got the other side from Rock Auto with that porsche part number earlier in this thread...amazing you get the boot, two clamps, a snap ring and two tubes of grease for less than $8.00.

    So how did it go? I am going to replace one soon. Did the Napa clamps hold and get tight enough?

    The napa ones come in one size, 8 of them for less than 10 bucks. Their tensioner tool is great. I just did the boots this last weekend. I too did not want to use the "fold over" straps that came with the boot kit.

    One other tip to keep the newly greased cv joints from picking up dirt or spreading grease on everything they come in contact with. Put a sandwich bag over the greased end of the cv and roll it back far enough to allow tape to hold the bag on the joint. Safeway sandwich bags are a good fit. Once the axle assembly is roughly in place, pull the tape and bag off of the joint and position it for bolt up.

    I used a bit less than one roll of papertowells to do this fun and exciting job:)

    hth,
    chris

    ps, as others have mentioned the cv bolts and nuts are probably rusted very tight. Use pb blaster a couple of times the day before. A good 8 mm allen is necessary, the cheap ones get loose and round over - ask me how i know. Clean out the allen inhex, so the allen can fully seat. I was starting to round over the nuts with an end wrench and gave up and got a pair of vise grips - they were just barely adequate to hold the nuts from spinning while trying to loosen the allens.

    Reassenbly is eased by a thorough cleaning of the bolts and nuts.
