Swapped the drivers seat belt unit I rebuilt a while ago.  Had to pull up the side plastic liner to get to the hardware

While I had the hatch open, one of the bumper/aligners was jacked a little.  Pressed it down and it popped out.  Slider tabs broke off from age.  A chunk of the tab is the small piece in my hand.  Pen to the upper right shows where it came from.

I had been grabbing pieces off junked cars for as long as I can remember.  I store the parts in a climate controlled room hopefully slowing the degradation process.  Over the past few years, I've finally been able to consolidate the parts together and create an inventory database.   Now i know what I have and where it is.  The spring launched out as the part popped out.  Luckily was able to find it.

Grabbed the worst of the parts from storage.  There's a crack across the bottom in the center of the replacement part, but the tabs looked good.  Laying them side by side, can see the years of impression set into the right side of the part to the right, where the pen is pointing.  I'm sure someone is making SLA's of these by now.  

 

Its a challenge maintaining an old car w OE parts driven/used so much.   Perpetual repairs.  Metal parts..  fine.  Its the plastics and rubber.  Then exposed to the southern sun or heat soaked engine bay.  Not a favorable condition.

CV AXLE JOINT DISASSEMBLE AND OBSERVATIONS.......

 

Brief summary.   More detail on this link 

 https://www.redpeppe...ack#entry580243

 

 

INNER SHAFT JOINT

 

 

53540044180_0f350317ac_c.jpg

 

This is the inner joint housing of a remanufactured axle I took apart in 2020  (far contrast to the inner housing that was perfect in the preceding posts from a couple weeks ago).   Can see where the reman company ground the outer race.   I see little wear over the section my pen is pointed to.  I assume it wasn't in service long.  Doesn't look that bad considering  they did the resurfacing by hand as noted by inconsistent grind pattern.

 

53539948094_b4d24951e5_c.jpg

 

This particular slot of three was ground the most and had a slightly over sized needle bearing in it (.005" over).  This bearing marked w twistie, (twistie is holding the bearing together as I removed the circlips to disassemble) wouldn't fit in the other 2 slots.  Issue here is the bearing wouldn't slide all the way into the housing slot it was machined to fit and sticks right at the point you see it in the pix.  Their grinding wasn't done in parallel.  Interference would cause excessive grinding of metal, shortening the life of the joint.

 

This explains to me why reman axles feel gritty and far from smooth as I rotate them new out of the box.  The inner housing is the simple one to grind.  The outer joint is complex geometry you'll see below.   This is why I sure don't want to use a reground outer joint.   Someone in the shop eyeballing w the grinder.

 

 

OUTER JOINT.

 

The outer joints are not supposed to come apart per Honda.  I'm pretty sure reman companies us a hydraulic press to yield the square cross sectioned circlip holding this joint to the shaft. This particular shaft came from an unmolested HONDA OE joint that was smacked hard enough to crack the knuckle.   Assuming the joint was bad from impact, I took a hammer and was able to whack it off the shaft

Marked the joint components.  Critical to tap on the joint where the 3/8" extension bar is (between the balls).  then the balls pop up enough on the opposite side to get them out w a small screw driver.  They pop out w moderate force.  Also note where the screw driver is....  the first ball has to come out at this casted-in feature of the cage.

The balls actually interference fit into the cage.  See the small divet ground into the  cage where the ball rests. You can see where the ball popped out of the divet and left marks side to side while in use.

Here's a pix of the inner race.  There are 2 distinct wear lines here where the ball worn into the race.  I'd assume over time as this wears deeper, this causes the clicking in the joints as the balls roll in and out of the wear path as the joint rotates???

 

I know both of these Joints were Honda OE.  The inner was reground.  The outer was virgin.  I found tool markings from Honda's sub suppliers to identify (stamped into the housings)

 

AFTERMARKET JOINTS.

 

Searching the net for aftermarket joints a few years back, there were several options  back in the day.  I go way out of my way to steer clear of cheap chinese crap.  Much rather over pay for parts made by reputable companies.    Making sure even the metal doesn't come from China as best as I can.

Heres a Joint from Germany by a company called Lobro.  Now I have no idea the build quality until I install and see how they wear.  From the image, the heat treating is obvious.  Honda appears to have heat treated the entire joint, not just spot treated the inner inside bearing contact area of the joint.  Note in the pix where the pencil points to the circlip.  This circlip has a rounded cross.  So the Lobro was designed to  pop off the axle easily.  The Honda is square and its not designed for removal.

 

Someday, I hope to remove good  Honda OE outer joints, reverse them and place on the opposite shaft (drivers to passenger and vis-a-versa).

Cool to get you car next to Hondas Mugen!,   Watched the video.   Awesome!!!!

Car cleaned up really nice.   It’s in really great shape


In Topic: 87 Crx Honda Cv Axle Joint Rebuild, Slop/backlash New Vs Used

02 March 2024 - 02:48 PM

I was exploring after market cv joints.  Couldn’t find anything on the inner joints.  Found several part numbers for the outers.  Appears mostly from European market.  I bought some Lobroes from Germany.     Made In Germany.  Hoping their reputation for metallurgy and tolerances holds up.    These are shelved for now.   But figure it’s an option to replace my outers.  Other brands were available, but couldn’t the where they were made on the packaging.  So I didn’t get any others.   I’m sure I have plenty of used axles to pull from to remake several sets of quaility axles to support my cars.  As long as the boots get replaced quickly upon failure, should get 200k out of these Honda axles

Notice the heat treatment from the inside of the housing.   I’m certain Honda heat treated the entire joint as I could could not metal stamp numbers into the outer housings of Hondas as mentioned before.  Flattened my hardened stamp.

 

 

The Lobreo joints came apart very easy.  Just grab the cage, rotate 90 degrees and the balls fall out.  No tools needs.  Feels like the Honda OE joints are more stout

INNER RACE OF OUTER JOINT

 

 

 

53539975699_a035251c49_b.jpg

Pen points to grooves worn into the drive side of the inner race.  I expected the wear area to be uniform over a small area as the bearings slide back and forth in these slots making 360 rotations under load.  Assuming 6 ball bearings yielding uniform load.

 

 

 

 

 

OUTER RACE.  / HOUSING OUTER OE JOINT

 

 

 

 

 

53538768357_07190786d7_b.jpg

Similar wear marks on opposing sides of the grooves machined into the outer housing.

 

This outer housing came off my CRX #9 I bought outright from a junkyard before anyone else picked off it a decade ago I’m certain this was the original axle outer joint from a 129k car.  
 

This car was not drivable.  And the inner joint was pulled apart from the heavy impact.  So I have no idea how this axle drove prior.

 

 

I’m thinking these grooves worn into the races must cause the “clicking” as the joint wears???

 

 

MEASUREMENT / BACKLASH ERRORS

 

At a later time, I’ll pop this on a shaft wo the circlip and measure it to see if I can quantify

 

Looking at the inner housing, it feels like the boots help the joint close to the position where the wear of the inner race/grooves would have occurred.  I believe the inner joint mesurement are decent.

 

The outer joint has specific grooves worn in the races by the bearings.  My measurement set up places the shaft in axial alignment to the shaft.  So the bearing  are most likely no in the grooves shown about into the races.  Best I can do at this time.
