Another successful day at the garage. I replaced the auto free wheeling hubs with a set of manual locking hubs from Superwinch (p/n: 400543).
The benefits of locking hubs include better fuel efficiency, quieter operation, less vibration, and lower wear. However one of the main reason to install manual hubs is you can engage them when you need them without moving (usually a whole wheel turn, normally in a specific direction) the vehicle. They also do not disengage, doesn’t matter in which direction you go. The only downside is you have to get out to turn them on or off, which is not a big deal for us.
The install went quite smoothly except of two stuck bolts which is not a surprise with an 16 year vehicle. Heating the bolts upwith a propane torch helped. Another item off our list. Here are a few photos of the modification:
Next project:
I still try to find the best solution to replace the left side lower control arm bushings. Not sure yet if I just should get new bushings and find a place which takes the old bushings out and press the new ones, or maybe buy a whole control arm. Anyway we need to get the alignment done soon. It is off quite a bit and you already see uneven tire wear. Any suggestions?
