Yes, as long as your 6 hub bolts aren't frozen in place. Mine were so I had my local mechanic do it.



No, although a pair of snap ring pliers are helpful.



Disconnect and tape back the electrical connector to the vacuum soleniod. The vacuum soleniod is located on the fender behind the air filter. The electrical connector comes up from the bottom. Leave all the vacuum lines by the soleniod in place. Remove the vacuum lines in each fender between the fenderwell and the hub. You can leave the vacuum line in the fenderwell open. It does not have to be plugged because no vacuum will be drawn since the soleniod is disconnected. Just cut off the vacuum lines at the bracket on the strut. You MUST plug the vacuum port on the back of the wheel hub. I used a screw with waterproof automotive goop glue.

If you like the amenity of automatic operation and you are decided to avoid abuse, the mechanical auto are fine: mine work perfectly in that context and will last because I know their limits and will not go over. If you have a bargain on them, do not forget that they come as a kit containing 4 parts for each side: hub, spindle nut, lock pin, cam activator. ALL 4 are essential. I have posted the installation instructions with photos at www.avigex.ca/hubinstall

If you live in snow country where you'll be driving significant distances in 4WD and on road I recommend you skip the auto hubs and go directly to the manuals. I speak from experience. I had the older 95-97 style autolocking hubs for about 4 years and one of them started to get funky about a year and a half ago and this past December destroyed itself. I never used 4WD on dry or wet pavement and always insured against driveline lockup in tight turns by shifting to 2H.

I have had the manual hubs for, oh, probably around 3 years now. I have done a LOT of offroading, nothing as hard-core as Dave, but my hubs have had zero problems. I think they are a lot more reliable and rugged than mech-autos.

One thing and one thing only.
When wou lock them (manualy) they will remain locked until the end of time.

No eng-diseng, ratling, one wotking other not ant staff like this.
My brother in law dicovered that after all he doesnt have blown hubs but a pump that was enganging without having engage 4wd....

Lou,
Please check your internet link. I lock up when trying to access it.

thanks

I agree, this is not a religion for me: if I did offroading, I would opt for the manuals.

This is a .pdf document. DO you have Adobe ACrobat Reader installed? You need that to be able to read.

Ok..indeed..I could not access it this morning although all was OK yesterday. I have updated the website and I access it normally now. Try again...

Lou,

For the Vacuum auto hubs (1998 & on)does the Warn manual hub kit come with a new hublock assembly which replaces the original one (step 11 of your installation PDF)? I am assuming that you now have to get out of the car and lock the front hubs by hand, a procedure which was not required on the original vacuum hubs. Can anyone post a picture of what the replaced hub & wheel looks like.

thanks,
Hamk
