just filled the rear gear(differential)? with sae 80 and it is still slipping and not catching the gears~~~~~!!!!!What now?I am not aautomotive inclined,naturally but can learn...Do I need a new rear Final gear case????Differential???PLease help....
Ah. Well, then it sounds to me like the differential is toast, but I'm not completely certain. Perhaps not having oil in the diff is a good indicator, but someone else will be along to give you more guidance.
Yes, I'd say the rear gear diff is toast. Is this a 4x4? If so, engage the front diff and see if it moves. Also, drain the oil from the rear diff. Catch it in a pan and let it sit for a few hours or overnight. Run a strong magnet through the oil at the bottom of the pan. Look for shavings on the magnet. Slowly pour out the oil and look for shavings in the bottom of the pan.
You will most likely be replacing a ring and pinion gear. If you're not mechanically inclined, have it done professionally...it will require shimming, seals, bearings, etc.
Check out hondapartsnation.com, best prices that I have found. Replaced the rear diff on my 04 rincon for 350.00 plus shipping. It's not much more than replacing ring and pinion and was a whole lot less technical work. Don't know anything about the recon but should not be much different, pull the old one out put the new one in. No, I don't work for atvpartsnation, have just had good luck with them. Ya gotta pay to play!!!!!
The rear ends are basically the same. The EX rear end may be geared a little higher. I have one of each but I'm not sure if the difference in the gearing is all in the rear end or in the transmission. The recon has an extra bolt boss on the left hand axle tube mounting a trailer hitch. But I believe they are basically the same and should interchange. Someone else may have actual knoweledge of the swap and please correct me if I am wrong (being I have one of each it may be good to know for future referance)
