    Axle shaft replace

    Hi everyone,

    steering is finally done and is much better after replacement of the rug joint and pitman arm. However when I was in service, the mechanic noticed that from the left brake drum is leaking differential oil. There was also little play when he moved the rear wheel up and down. According to the mechanic, the axle shaft, bearing and seal has to be replaced - but he did not checked the axle shaft, he just saw the leaking oil and tried the play of the rear wheel. Regarding the fact that axle shaft together with the shipping is not as cheap, I would like to ask you, if it is necessary to change it, or there is posibility that just the bearing is worn out. Would you recommend to check the axle shaft first as it could be OK and just bearing could be worn out or is this check pointless and the axle shaft shall be replaced anyway? I had similar problem with leaking differential oil cca year ago and it has been solved by the replacement of the seal. Many thanks.

    "repair" bearings might be a good choice for you. They have a built in seal, and ride on a seperate place on the shaft. Just doing the bearing and seal might fix the problem, only way to really tell if you need an axle is to pull it out. (I've replaced everything on mine and it still leaks)

    Generally, the right side ruins axles. Not the left. So, if you can locate a junk car, you have a good chance of finding a good axle on the left side of a junk car.

      What he said. Usually when the bearing is worn, there will be wear in the axle as well. The repair bearing should allow you to use your existing axle. Here in the US a standard bearing is about $10, and the repair is about $25. The axle is about $130, so the repair bearing would be a cheaper option to try at first.

        Yeah -- repair bearings would allow you to use your existing axle shafts if they are worn. This type of bearing is offset so that it contacts a fresh unworn area of the shaft.

          Honestly, I reinstalled two "bad" axles (pitting in the bearing area) on my '79 after installing standard bearings and seals and experienced no issues. I didn't put a huge amount more miles on the car, though, and the repair was more a cheap way to stop the klunking noise the car had developed.

            Pitting you can get away with, but sometimes those axles will develop noticeable grooves at the bearing and at the seal, which is just no good. Pits make noise, deep grooves make for busted axles and/or leaks depending where they are.

              I know this isn't a Ford, But my Chevy Caprice policecar had the same issue... it was so bad, we had a hell of a time just getting it out of the car. There was a nice groove all the way around the axle shaft... We tried to find a new one, (Junk yard) But none were available locally... So we opted to put in the repair bearing... It went right together, and I drove it over 100,00 miles with absolutely NO bearing noise, and no more leaks from the seal.

              I saw the car the other day in town, and talked to the guy that owns it now... it is still running like a top, and he never mentioned any problems with the axle. All he has replaced since he has had it has been a new smog pump, due to bearings. I sort of miss that car... It was a special order Police package car... The Okaloosa Sheriff's Dept. ordered it with the 4.3 V-6, since it was a jail car... Got good gas milage (I could drive from here to Nashville, Tn., 450 miles or so, on one tank of gas, going 85-90 miles an hour all the way, did it once on Thanksgiving morning, going to see my cousins!) I sort of wish I still had that car.... It only had 38,000 miles on it when I bought it...

                thank you very much for your answers. I have read about the repair bearings already but on one site few pepople said that they are not good at all and that they can damage the axle.. Has anyone experiences with them? I will definitely first check the axles what they look like.

                However I tried to find the axle repair bearing in some on-line shop or eBay and I was not succesfull. Do you know any place where it can be ordered (online with shipping to Europe..)?

                  I tried them on my car and it didn't fix the leaking problem, but my axle was bent. I've seen them used on several other cars without issue. Generally speaking, if you're using a repair bearing the axle is already damaged so you really have nothing to lose.

                    I am not a mechanic. But I do have a degree in mechanical engineering -- not that it means anything. But I can see how using a badly grooved axle shaft with a repair bearing would be risky -- especially if you hauled a lot of weight in the car. Firstly, if the groove has sharp edges, it creates a stress riser that could create a starting point for a catastrophic crack to form in the shaft. Secondly, if the groove is significant (as they were in an old Fox body I used to own), then the axle is effectively reduced in diameter where the groove is, which can cause a weak point. Thirdly, the groove will be really close to the point where there is maximum bending stresses on the shaft. All three of these factors put together seem to point to a slightly risky situation from the standpoint of breaking the shaft. But on the other hand, it seems like if there was that much risk involved, the repair bearings would not be sold because it would create too much liability.

                    Short answer is -- I don't know.

                      Valid points, I think it probably has to do with how bad the axle is. If its really got a deep groove, the proper way is to replace the thing. If its just rough and has a slight groove where the seal sits, its not really significantly weakened from an intact axle. I have seen pretty deep grooves in these axles before, so it is possible to have substantial wear that is cause for concern.

                        I definitely agree

                        yes, I agree that the condition of the axle would be the main factor in a decision to use the repair bearings. Slight wear or surface imperfections shouldn't be much of a problem.

                          Finally the job is done, new axle shafts and bearings and the car rides great. I had to drive car with manual transmission two days and it was really terrible, I really missed my marquis Thanks for your help
