I just bought an 89 Jeep YJ with ARB Lockers (which don't work) and the stock rear end (Dana 35C). I have heard a lot of bad about the Dana 35. The jeep has 35" tires which I know contribute to the problem but how bad is the original axle? I won't be doing trails or rock climbing and got it mainly for the beach. Would it even handle the sand or should I consider the other popular axle alternatives? I would like to get the ARB lockers working but ARB cautioned me about spending too much on the old products. All opinions are valued. Thanks.
