Rear End replacement

Well, I read all about it and knew I should have lubed the splines. The mechanic told me today the rear end was gone and it was a $1200 repair. I've read on here of people getting lucky and finding the parts for $150. What parts should I be looking for? Do I just search for "Vulcan rear end?" Thanks in advance, Andy

If you have a manuel or have pulled the rear tire at one time, or you can check the threads as for how to remove the rear tire. It is really not hard, just follow the easy steps. You should pull it apart and see what is really wrong with the drive. You may only need a new drive shaft, these you can find on ebay or somethere person from this sight may have one. Do not take the dealerships word as for what is wrong with it, they, I assume did not even take it apart. Try and take it apart and maybe do it yourself.

Hey Andy, update your profile when you get a chance. Where are you from? Lots of people here, it's possible if someone is close by you they could give you a hand.

Im going to guess that you sheared the splines off of the pinion shaft on the rear end, mine did that early this spring, hadnt been lubed. It is an expensive fix but there are salvage yards that can get you what you need. Just be sure to grease it real good when you put it back together.

Lubricate it with high moly grease such as Honda Moly 60 or equivalent.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

I bought a couple of them off ebay. Search for vn750 or vulcan 750 final drive. You'll also need the coupling that sits on the end of the drive shaft. You might find the drive shaft and coupling on ebay too. You can still order the coupling I believe from a parts house and it's not hard to change. It's not a hard job at all to replace them, and it's a good exercise to get you used to pulling it apart and lubing the splines anyway. Scads of us can help you verbally or there might be someone close enough to give you a hand. Just be patient. It might take a little while to find your replacement parts. Insist that they send you photos of the splines on the final drive (shaft end) and of the inside of the coupling before you buy! Most of the parts bike guys on ebay don't know the significance of the shape of the splines!

not meaning to hijack but how prone are the !500's rear splines to failure,Fergy? I am getting ready to,pull mine before long and do a lube job,and replace the front tire as well,Metzeler this time the Bridgestone on the front is the noisiest front tire I have ever owned ,It has plenty of tread but is starting to cup.
