no worries. besides, i'm not an expert by any means, and wont be surprised if many things i say are wrong. on the subject of hubs, i have a question...my 4x4 has been acting fishy recently. When it's in 4x4, the front end seems to "lock up", or feel as though it jumps or hops a little. it seems to do it most going about 35, and does eventually go away, any ideas? i bought a new hub assembly thinking that was the case, i was told it might also be the halfshaft, but that doesn't sound like it to me.
