My right rear bearing is making noises. I called my mechanic and he said to get parts and he would install it.
I am looking at the exploded view of rear axle. (See below) When I order parts, do I just need the Bearing #28? Is there a race for the control arm because I don't see one? Does he need to remove CV axle and tap out the bearing from the inside? Thank you in advance for your help. Attached thumbnail(s) ![]() |

You just need the bearing, its a sealed unit so the bearing and races are all one part

Just the bearing! (IMG:style_emoticons/default/beerchug.gif)
You might as well replace the bushings also while your in there!! |

CV has to be removed, along with caliper and rotor.
Hub will have to be removed first or after bearing and hub are pounded out. You need a tool to reinstall the bearing and hub. Without the proper support the bearing will be destroyed upon hub reinstall. |

You will also need a freezer and time to let it freeze for two days, or dry ice. You might also want a torch.

I read about the freezer trick earlier and was planning to do. Getting bearing tomorrow and will freeze until Monday! (IMG:style_emoticons/default/beerchug.gif)

If your mechanic is doing the work then he will need to freeze it because it needs to come out of the freezer and directly into the trailing arm before it warms and expands!
I leave a 60w light on the trailing arm for a few hours before and coat it with a light coat of grease. Then I put the frozen bearing in and most of the time it slides in like butter!! But if you wait to long it will stick and you have to finish by pressing it the rest of the way in! PS: It is way easier to do it on the bench than on the car! |

Made my own tool using pipe and caps from the Home Depot. Get pipe to contact the outside of the bearng.
Also used a BFH (IMG:style_emoticons/default/smash.gif) Then I used an extra stub axle to finish. Just one way Van914 |

I was going to pack it in ice before taking to the mechanic on Monday. He has a freezer and we will put in there while we dissemble the hub, CV axle, old bearing, etc! We will try to get heat on the trailing arm. It is going to low 30's Monday morning.
Thanks for the tip!

I've done them in the car but next time I'm pulling the arm so I have an excuse to buy a press. (IMG:style_emoticons/default/biggrin.gif)

I had no luck getting a bearing out recently - tried various versions of the homemade bearing pullers, tried a BFH, tried even a bigger BFH, still no joy, cried uncle and took the trailing arm to the shop and let them press it out.
If you are installing the hub vice your mechanic, don't forget to install the bearing cap (retainer) before installing the hub - failure to do so will result in stream of profanity and likely a ruined bearing. (IMG:style_emoticons/default/headbang.gif) |

I know this is an old thread but I saw something even older on another forum that I thought might be useful. I cant take credit, the author was someone named SammyG
bearings and any other parts that are designed to have an interference fit need to be installed in one of two ways, either with a press pushing on the correct place (either inside or outside race depending on where the interference is) or you need to temporarily eliminate the interference fit with temperature diferentiation. heat the outer part and/or cool the inside part and you suddenly have clearance until the temperatures normalize. What you should have done was to put the hub in the freezer and put the bearings in the oven and heat them up to around 230 degrees F. Then carefully slide the bearings onto the hub. Then put the entire hub with bearings in the freezer (inside a plastic bag) until it is cold then carefully insert it into the control arm. No hammers allowed. |

The correct schnorr washers for the cv bolts for when you put them back in.

.......No hammers allowed. ^ Agreed, If a proper press or extractor is not available,a hammer is the way to damage the bearing. Cooking the bearings in clean oil to above 212 F,more like 300 F,will allow the bearing to slip onto a chilled shaft. Both must be checked for actual dimensions and the resulting interference at operational temperature.SOP. Roller bearing crankshafts and spindles have certain required methods. Induction heating of bearings or housings is another way,production oriented. https://www.google.ca/webhp?sourceid=chrome...=bearings%20101 https://www.google.ca/webhp?sourceid=chrome...%20installation https://www.google.ca/search?q=bearing+pull...anSDP0Q_AUIBigB ![]() In the machine trade,smoking a 30K$ machine bearing is not an option,therefore expertise and experience is applied. / |
