straight6pwr Posted March 2, 2017 Report Share Posted March 2, 2017 you building your own half shafts? Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted March 3, 2017 Author Report Share Posted March 3, 2017 I guess you could say that. Since the shop in Waukesha (that I was referred to by multiple people) wouldn't shorten my halfshafts, I took it upon myself to get it done. They need shortening because I am running a medium case diff in a custom subframe I had made. So, my dad and I have been doing it periodically after hours and on weekends at his work shop. Just can't have the bosses seeing is all. I figure since I'm getting all that done, might as well clean out the CV joints and put new flanges/boots/grease in them. W&N was the only place that had a complete boot kit for the e21. Others just had the boot and clamps and would of had to buy the grease and such separate for practically the same price.

Earl Posted March 3, 2017 Report Share Posted March 3, 2017 How are you going to balance them? Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted March 3, 2017 Author Report Share Posted March 3, 2017 I hear Ray has a dynamic balancer at his work I will ask him about. Otherwise I will just take them to a driveshaft shop and have them statically balanced. The way we are making them, the fitment tolerances are almost 0, so they shouldn't be too far from already being balanced. The only factor that could potentially throw the balance off is how the welding comes out. Quote Link to comment Share on other sites More sharing options...
jc43089 Posted March 3, 2017 Report Share Posted March 3, 2017 Also the speed of the axle rotation is significantly less than the driveshaft. I don't think you would have any problem just running them. I might be wrong but wouldn't the forces rise at an exponential rate to the rotating speed? So if the rotation is 1/3rd to 1/4th the speed of the driveshaft depending on dif ratio the out of balance would have to be very bad to cause a vibration like an unbalanced driveshaft? Or you would have to be going 200+ mph. Quote Link to comment Share on other sites More sharing options...
B C Posted March 3, 2017 Report Share Posted March 3, 2017 150mph is going to be ~2000rpm axle speed Quote Link to comment Share on other sites More sharing options...
straight6pwr Posted March 3, 2017 Report Share Posted March 3, 2017 dave - i once took my first e30 to this truck frame and axle place when my rear frame collapsed at the spring perches. they did a good job, but the thing that stood out is they didn't care what kind of car it was they were willing to just get it done. maybe worth a call for the axle building/balancing?

Bassboy3313 Posted March 3, 2017 Author Report Share Posted March 3, 2017 Frame & Axle Services Co was the first place I went to see if they would shorten the axles for me. They don't do that kind of work and referred me to Machine Service in Waukesha/Pewaukee that I mentioned earlier. Them and a couple other people referred me to Machine Service as well, but they didn't want to take that project on either. This is why I am now doing it myself. If Ray is unable to dynamically balance them at his work, I was going to go back to Frame & Axle t osee if they can static balance them. A few people that had the idea of shortening their own halfshafts or have actually done it said they weren't even gonna bother balancing them anyways. This is more of a peace of mind thing for me it seems. Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted March 21, 2017 Author Report Share Posted March 21, 2017 So, I did a thing after a few guys here mentioned to try it. Tried out some lamin-x on my taillight lenses since new ones are crazy expensive if you can even find them. Turned out decent. Didn't hide the cracks and blemishes as well as I hoped, but still better than nothing. Debated on leaving the reverse light lense white or not (not like they work anyways). What do ya'll think?

straight6pwr Posted March 21, 2017 Report Share Posted March 21, 2017 looks great! i think it hides the cracks pretty well, at least in that photo Bassboy3313 1 Quote Link to comment Share on other sites More sharing options...
Daggerty Posted March 21, 2017 Report Share Posted March 21, 2017 #Insta famous like the red but if you could get rid of the amber marker and do red with just the white reverse.... coming from a e36 guy so that might be my reasoning. I can do the axles for you, I do a lot of welding I can give you some nice beads but you have to take your shirt off. Id be using a 252 millermatic.

It's all a one piece lens, so can't just get rid of yellow signal portion. As for the axles, they have been machined and are in process of getting welded already.

Bassboy3313 Posted March 21, 2017 Author Report Share Posted March 21, 2017 Axles all welded up. Time to get them balanced, painted and start assembling the cv joints. m42b32 and Jeff 2 Quote Link to comment Share on other sites More sharing options...
Jdesign Posted March 22, 2017 Report Share Posted March 22, 2017 The taillights turned out great. Nice job! It might just be my eyes, but those axle shafts look oblong, I would certainly make sure that when they are balanced, they are not off by a large amount. Maybe turning them in a lathe to make sure they are completely centric if that's the case. Quote Link to comment Share on other sites More sharing options...

Bassboy3313 Posted March 26, 2017 Author Report Share Posted March 26, 2017 Since mitch asked, here is what I had to do to "rebuild" the shortened cv axles. First thing was to clean all the old grease out of the cv joints. I soaked them in a can of parts cleaner for 24 hours then blasted them with my air sprayer in a can of mineral spirits. Blew them off with air hose and let them air dry. I taped off the mounting holes and inner spline hole, then proceeded to pack them with new grease. I used half the pack of grease that was included in my new boot kits from W&N. Once they were all packed with grease, I installed the rear cap and boots. It was nice that W&N pre-installed the boot and clamp so I didn't need to buy a clamp pliers. I put 3 of the mounting bolts through the holes to line it all up, then tapped it on lightly with a hammer. I then went ahead and painted the axles. Installing the joints onto the axles were tricky, but once I got the first done the last three became easier. With the remaining half pack of grease, I put half of that into the boot and the rest on in the other side of the cv joint. Slide clamp on, put axle through boot, lightly but firmly tapped the cv joint back onto the splines of the axle, installed c-clip, and tapped outer cap on with hammer, done. m42b32 1 Quote Link to comment Share on other sites More sharing options...

Bassboy3313 Posted March 31, 2017 Author Report Share Posted March 31, 2017 11 hours ago, Jeff said: What's next? Lots!!! Hoping tomorrow I can get the subframe and diff mocked up so I can mark where the diff hanger mounts need to be welded in. Make the mounts, burn them in and coat them. Then I can install the rear end for good after that. Still cranking away on the body work. Picked up some epoxy primer that I will be spraying all the bare metal with before doing the body filler. Been reading up on it and have asked a few body work guys and they all say the same thing. Whats left is welding up the holes for the rear side marker deletes, cut/weld the wheel arches for flare fitment, then fix all the small areas around the car. Epoxy primer, skim coat body filler, sand, sand and more sanding. Also still need to fix the fuel leak between the oem fuel line fitting and fuel hose to rail, fix the exhaust leak at the manifold (i'm suspecting), install the headlights, and finish control panel wiring. Once I get my tax return, tires will be first on my shopping list too. Jdesign 1 Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted April 1, 2017 Author Report Share Posted April 1, 2017 Subframe and diff are temporarily (possibly permanently depending on if they're in the way or not) installed, thanks as always to Brian's help! Ran into a few snags, mostly being the stock diff mount had to be cut out for the diff to fully seat. Got that done. Looks like I'll need to do some slicing and dicing to the frame brace. Diff hangers are already touching that brace and don't want any vibration problems. Plan of attack is sectioning the frame where the mounts need to be and boxing it all back in once the new hangers are welded. Welding/boxing it all in will give the rigidity back to the structure. Oh how I wish I had a lift to make this a lot easier. Sigh! Quote Link to comment Share on other sites More sharing options...
