Convert to real 5-lug using 944 CVsThis Article describes how to convert the rear axles on your 914 to give you real 5-lug hubs using a mix of 914, 944 and 911 components. Tools and Supplies:
Step 1: Preparing the axle shafts Remove the CV joints from your old axles and machine both ends of your axle shafts to allow the wider 944 CVs to slide on. You'll have to remove 4mm of material to make up for the wider 944 CVs. 4mm of material removed: Stock 914 CV on the left and a 944 CV on the right Step 2: Putting it all together Grease up your new 944 CVs and slide them on the machined axle shaft *without* using the stock spring washer behind the CV! Make sure the CV slides all the way on and don't forget to put the circlip back onto the shaft to prevent the CV from sliding off. Note: Make sure the "groove" on the outside of the new CVs always points away from the axle (see picture with the complete axle). Remove the old stub axles and hub. Remove the old wheel bearings. Install the new wheel bearing in your trailing arms. Make sure the bearing surface on your new hubs is clean and press in the new hubs. Install the new stub axles and tighten the axle nut. Remove the old output flanges from your transmission, replace the seals and slide in the new 911 flanges. Grease up both, the output flange cup and the stub axle cup and install your new axles. Don't forget the CV seals! Tighten everything to spec and enjoy! 911 coarse spline output shaft and 911 stub axle: 944 CV on 914 axle shaft: Test fitting the output shaft on the 944 CV: And at last, the completed axle.

Aaron , I'd love to get a set of the 944 axles ( these are for the auto trans ?? What year ?? ) . That way there would be no need of machining the 914 axles and have the full length of the 944 spline on both ends . the spacing thing was an idea just in passing as someone earlier in the this thread mentioned using 944 axles that got into a bind on them. I'm using 911 SC hubcentric wheel hubs and have a choice of using 911 SC cv stub axles or 944 stub axles. The length of the 944 auto axles is very interesting as it would'nt be a big problem of making a spacer to space out the stub to make up for the 4mm difference if one so chose to do so , yes you are right about the 4mm not being a real deal breaker as it would only come into play at full droop or rebound up of the suspension . Please keep updating this thread with your findings , as the use of the 944 auto axles hasn't been covered and would be a great addition to this sticky.MHO.....
Jack p.s. I think most folks here have made a blood offering to our cars at one time or another , and usually a continuing deal with the car Gods.... (IMG:style_emoticons/default/pray.gif) |
