  • Good Parts CV Axle questions

    Hello folks - firstly, hoping all of you remain fit and healthy!

    I'm considering pulling the trigger on a set of GP CV Axles. This is mainly as I believe my stock axles/hubs are on borrowed time. One of the hubs has once again developed noticeable play in it, and I believe I have worn splines on one or both sides. Also, the annual "greasing of the splines" routine is a PITA.

    A few questions for those of you that have them:

    The GP website indicates some grinding of the TA is necessary - how extensive is this, and what exactly needs to be ground?

    I'm assuming that the CV axles are effectively maintenance-free units - or are there any maintenance tasks?

    Any noticeable improvements in noise, handling or performance, etc. vs. the stock axles/hubs when in good condition?

    Hi Bama:

    I installed the GP CV Axles 10 years ago. From what I could see from inspection, my axles and hubs were in good shape but I had no idea of their history. I upgraded for strength and long term trouble free heavy use.
    1. I had no grinding.
    2. No maintenance has been required.
    3. There was no noticeable changes in noise, handling, or performance.
    I feel this is one of those upgrades that is performed and not have to look to this area ever again.

      When I did the installation several years ago, I used a rotary type sander and smoothed the few high spots inside the trailing arm. Not very extensive and with the soft aluminum is went very quickly. I assume CV maintenance would be the same as other CV installations. I installed the Nissan LSD as well as the full axle/hub set up and I think i noticed the LSD more than anything, but it is quieter as the splines were definitely worn. I am glad I don't have the u-joints to fail or become noisy when grease level is low.

        No grinding on mine.

        i had my hubs rebuilt by Phil and had new u-joints in the axles. But i wanted a smoother ride for highway traveling. I noticed a much smoother ride after installing them.

        Also, I bought mine from Rimmers. Because they were quite a bit cheaper. Of course after shipping, they weren't so much cheaper. And I doubt i can install a Nissan LSD with them should I want to........

          I also had my axels replaced, this year, with CV's from Rimmer Brothers and no grinding on TA's. My old original axel splines were worn and exhibited a loud "clunk" on take off. The swap to CV's fixed that and I also believe had less friction (from hubs, axels etc.) as my acceleration improved. I don't know the difference between "Good Parts", and Rimmer. Maybe someone here can help answer that.

            Bama:

            I should have been more descriptive in my post above. My upgrade was the complete CV Joint Axle and Hub Assembly, not just the hubs. This assembly was mated up to an earlier installed Nissan diff upgrade. Now, as camtr6 mentioned, I too noticed the LSD after its installation; the car just wanted stay straight.

                Thanks for the comments so far chaps - Seems like the grinding required is pretty minimal, so that is good news. Also, some anecdotal evidence of smoother/quieter operation too, which would be welcome. Mainly I just want a stronger, smoother and safer alternative to stock hubs, along witha minimum of maintenance.

                Also appreciate the tips that these are available from Rimmers - I wasn't aware they sold them. Looking at the Good Parts hubs vs the Rimmer alternative, the GP version appears to have a meaty alloy flange on the hub - not sure if that's just the image though. Also, I like the ability to be able to convert to the Nissan Diff, which is on my longtime road map. So, Think I'd be more inclined to source from Good Parts - Not that I've had a problem with Rimmers' quality, but, I did have one item that I wanted to return (a convertible top), and found that process to like pulling teeth. Whereas Richard Good stands by his stuff, and makes things right.

                  To add about grinding, I cant' find it now but I think I recall the GP instructions saying your installation "may require" not shall require grinding of the TA. I recall this because I was relieved that when tested I had no movement interference; no material to remove. My only comment about GP return policy is Richard picks up the phone and quickly resolves any conflicts.

                    A little something to read about the Rimmer product although for these they appear to be a re-seller.

                    This is also just one persons point of view but just for what it is worth.

                        I installed RG's rear hubs a couple years ago but kept the original axles. I just replaced the U joints in them before I put it all back together. No grinding of the trailing arms needed of Click image for larger version

                          I also had no grinding involved with the installation of the CV axles. I did notice a big improvement in the vibration I had been chasing in the car for years. I made a couple videos of the install.

                            Hey Keith, I installed RG's full CV axle sets in both the 76 and the 250. No mods to the TA in both cases. (My 72 already had the CV axles as done by the PO)

                            Both cars also have the R200 diff and Richard is great to work with. The most noticeable difference in the 76 was a much quieter and smoother ride. (The 250 is still under construction but I'm sure it will have the same smooth ride)

                            I'd go for the new diff now, (while you're in there), as Richard told me the low mileage ones are getting harder to find. JMHO

                            Cheers,
