So i am in the market for a new rear end for my 67 Monaco

found a guy selling a 8 3/4 for a "c" body for $200

what should i look for on it to make sure it fits?

i know my car came with a 8 3/4, but i would rather spend $200 on a new rear end with new bearings, seals, and studs, then replace al those same things in mine.


thanks

I think you would be better off pulling your axles and having new bearings and seals put on rather than replacing the entire rear end.With something used the seals and bearings are likely to need replacing anyway.just my .02 worth.

 

I would take some measurements just to be sure. Total width and the width between the spring perches. These need to match. Are you sure that all the bearings and seals have been changed. Show the reciepts and make sure the bearings are the correct tapered roller bearings, preferably Timkens. ALso, the inner seals need to be changed. This is the seal in the axle tube towards the outer ends of the axle tubes. Also, the 8 3/4 has wheel bearings that are greased like a front wheel bearing, not by the axle lube. Make sure this was done. also make sure the axle play adjustment was done correctly. I guess what I am saying is that all of this stuff needs to done right. 8 3/4 rears are harder to set up right but are bulletproof once you get them setup. In my opinion, the "green" replacement bearings are not a good option. I would not have them in my 8 3/4. If all these things were done, than $200 would be a steal, but if something was overlooked or done incorrectly then you wlii have trouble down the road. (I know long answer for a short question)

 

I would rather replace everything in my *ahem* rear end than trust the word of someone you don't know. Receipts aside, if the guy doesn't have some references (like your friends, perhaps, or is this his job?), I would be really careful.

If you do it yourself (or have it done) then you do get the choice of selecting your own grade and make of parts.

Just because "it's already been done" doesn't mean it was a good job, or quality parts were used.

I'd spend the $200 on ordering your parts online (for best prices) and make at day of it with some of your buddies. Elbow grease goes great with burgers and beer.

 

right on.

i figured there was a ton of variables. all of the parts in this rear end are new, it was built for a A body but the owner did not realize the difference (hmm)

i would not mind rebuilding it all with some buddies, but none of us have a clue about how to do it, is there a good "how to" with that particular rear end?...my major problem is a leaking wheel seal which has caused one of the brakes to seise up. i do not want to drive it the way it is, if someone has a good site with the right pieces to order that would be helpful...i would love to "rebuild" the whole thing while it is out!

do i need to have the new bearings / seals pressed in?


thanks guys, sorry for the mass amount of questions

heres a link to the expired ebay ad, but i contacted the guy via phonecall and it is still for sale

 

i'm with morrigan on this one
just replace whatever is worn on yours

 

that seems like a good buy as long as it's done right .

 

I don't care what the guy says, you should always ask for receipts of parts bought and from the shop that did the work. If the guy said he or his buddy did the work, Then I wouldn't trust any of the work done. Inspect it before money changes hand. Make sure that the axle splines are not twisted, the housing is not bent, etc.

You can buy a full rebuild kit for your axle for probably under $200 shipped with good quality bearings (Timken bearings are what I use and they are made here in the USA). you get some good quality axle shaft seals and be careful to install your shafts and you should not have a problem with them leaking again on you.

With so many people needing axle work, I wish I was closer to everyone.

 

Morgan is right just replace the bearing and seal. there is a building down the block called the Library and the person in there will help you find a book that will help you repair this problem and it will be a lot less expensive and save you down time
PUT SOME GREASE UNDER THOSE FINGER NAILS

 

like i said, i have no problem doing the work...i just thought they needed to be pressed in. if anyone has a link to a trusted rebuild kit, i would gladly spend the money on that...the first thing i asked the guy on the phone was for receipts, he said he would look and get back to me on monday, but if i can rebuild mine for the same price, i would rather do that and learn how to do it

thanks

 

You can check Summit Racing online. With a few minutes, I found this: http://www.summitracing.com/parts/DC...n/?prefilter=0

I would suggest you CALL them. 1-800-230-3030. They have more items available that are not shown online. Specify what you want, like US made parts, etc.

And finally, using MY internet skills, I found this: http://www.moparmusclemagazine.com/t...dup/index.html

We're all here to help, but we can't do it for you. A little simple word searching in Google or Yahoo is really all it took.

 

That is a good kit for the axle seals that Morrigan found. You couple that kit with a bearing kit, and you can rebuild your axle for the same price as that housing only. You just need to keep everything separate when you take it apart and make sure that it goes back together the same you as it came apart. your bearing caps even have to go on the same way that you took them off. You will need a bearing puller, or something like it, to remove the old bearings off the carrier, and a press to get the new ones on.

What you go with for bearings though will be determined by which case you have. I'm not 100% sure but the cases may use different size bearings.

 

i agree, and thank you

i actually found the same results..


i wasnt asking for anyone to do my homework for me, just thinking if people who do it more often had a source that has been rock solid, i have about 10 sites bookmarked already


thank you

 

Summit has been pretty good to me, but they ARE NOT Mopar fiends typically.

Since MP makes the kit too, DO NOT HESITATE TO CALL THEIR TECH LINE. VERY knowledgeable folks. I called them about repro Max Wedge heads and they even sent me off to another expert. They can also make sure you get the RIGHT parts, so have your casting numbers etc available; ensure you have correctly identified your rear axle size! You cannot order directly from them, but they'll give you the part/kit number and you can find a supplier from there.

If you have a local Mopar club, someone there would probably be at least willing to lend you some tech experience. Out in my neck of the woods, I've found ALOT of old retired mechanics who could do this in their sleep. Many are too old (in their 70's, so I don't want to hear any grousing that anyone is too old) to turn the wrenches themself (and it's YOUR car...), but are MORE than willing to provide tech help and advice and sometimes even a shop bay and a few tools to help you out.

If you've been doing your own research, good on ya.
