Car Forum / Chevrolet / Chevrolet Trucks / May 2005Manual vs. Auto Locking Hubs
Hi All, Can I convert my manual locking hubs to automatic without a kit? Maybe by going to the junk yard and puchasing auto locking hubs from a truck of the same frame and year? Thanks. Jake What year of truck??? > Hi All, > [quoted text clipped - 4 lines] > Thanks. > Jake Sorry, it's an 87 3/4 ton. > What year of truck??? > [quoted text clipped - 6 lines] >>Thanks. >>Jake Yes you can. Just make sure to disassemble them and clean them thoroughly and reassemble them with no lube. > Sorry, it's an 87 3/4 ton. > [quoted text clipped - 8 lines] >>>Thanks. >>>Jake There's no vacuum lines to connect or some kind of solenoid to run a new wire for? Admittedly, I only want the convenience of not having to lock the hubs in myself; is there an advantage manual hubs have over auto? > Yes you can.

Auto hubs DO work in reverse...they are actuated off of pressure, NOT direction! Forward or reverse, they DO work if everything is clean and functioning. The advantage of manual hubs is that there is no question when they are locked and unlocked. Auto hubs got a bad rap when they get wheel bearing grease in them and hang-up either locked or unlocked. I like manual hubs for warmer weather when I am going to be doing allot of hard off-roading and auto hubs for winter weather(I live in NW Iowa) when I just don't want to get out in the cold and usually only might need them for 100ft...getting out of the driveway, getting someone unstuck, etc... It ALL comes down to personal preference...and the fact that auto hubs DO require at least a once a year cleaning. >> There's no vacuum lines to connect or some kind of solenoid to run a new >> wire for? [quoted text clipped - 5 lines] > > manual hubs work in reverse.......................... really then why does the manual tell you to back up to disengage them ? > Auto hubs DO work in reverse...they are actuated off of pressure, NOT > direction!

If its in neutral there is no load from the front axles to the hubs. I have run auto hubs for years and I KNOW they work in reverse! So do many people I have known over the years. And by the way, you can unlock them by going forward to with little trouble...and going 60MPH! > really > [quoted text clipped - 27 lines] >> > >> > manual hubs work in reverse.......................... look, Braniac if they 'unlock under no-load', they cannot work both forward and backwards one or the other direction will make them unlock think about it > Transfer case in neutral!!!

WOW, after all this time reading your awesome posts in this NG your true maturity comes out. They work no matter what your inexperienced, uneducated opinion about them might be. I and millions have used them over the years and for years and THEY WORK! Forward AND backward because they are actuated by load! The ONLY reason they have a bad name is because they don't work when dirty and/or greasy. Complain and belittle all you want, it wont change the facts! Have a nice day! > look, Braniac > [quoted text clipped - 47 lines] >> >> > >> >> > manual hubs work in reverse.......................... no, my frustration at folks who cannot comprehend a simple mechanical concept over-rides my ability to be civil to those folks you can't have it both ways: either 'load' actuates it forward and lack of load releases it backwards, or 'load' actuates it backwards and releases it forwards what the hell do you think is in there, a tiny brain that says 'uh-oh, we're going backwards, but ole 'shades' is in a tough spot, better stay engaged' ??? stop and think about what you are suggesting, fer shitsakes > WOW, after all this time reading your awesome posts in this NG your true > maturity comes out. [quoted text clipped - 60 lines] > >> >> > > >> >> > manual hubs work in reverse.......................... I have to agree with Shades.My auto hubs shift in and out with the lever in the floor.Bobby There might be a moment when there is no load when shifting into reverse, but they do work then the vehicle is in reverse, at least for the auto hubs that I have used since 1988 on a Scout, they will lock in reverse. Warn hubs with IH logo on them. They are more complex than a simple over-running clutch. I maintain them myself and had to study how they work when I put too much grease on them one time. >no, my frustration at folks who cannot comprehend a simple mechanical >concept over-rides my ability to be civil to those folks [quoted text clipped - 161 lines] > > Thanx guys...my point supported. > There might be a moment when there is no load when shifting into reverse, > but they do work then the vehicle is in reverse, at least for the auto [quoted text clipped - 117 lines] >>>>>>>> >>>>>>>>manual hubs work in reverse..........................

With an allen wrench and snap-ring pliers for outer rings, its about a 15-20min job. > Since you trade them out frequently, are they pretty simple to install? > [quoted text clipped - 20 lines] >>> >>>manual hubs work in reverse..........................

I must have struck a nerve... > Thanks for the advise, sorry this thread turned ugly. > [quoted text clipped - 27 lines] >>>>> >>>>>manual hubs work in reverse.......................... I think I'm with Shades on this. Manual for the warmer weather and harder driving. Auto in the cold for the convenience. When I switch them out I can clean and maintain one set while the other set is on. I'm also looking forward to seeing first hand how they come apart and fit back together. Now, to find a good set at the junk yard. How much should they cost?? > Auto hubs DO work in reverse...they are actuated off of pressure, NOT > direction! Forward or reverse, they DO work if everything is clean and [quoted text clipped - 18 lines] >> >>manual hubs work in reverse.......................... I wouldn't pay any more than $50 for a good pair...make sure you get EVERYTHING! Also, make sure you test them immediately and that they will take them back if they don't work! Get stainless steel hardware to use for ease of removal. >I think I'm with Shades on this. Manual for the warmer weather and harder >driving. Auto in the cold for the convenience.

I found that new manual hubs are almost as cheap ($65-85) as used ones ($55-80) if you catch them on sale, depending on brand, etc. Then you get instructions and a warranty. > I think I'm with Shades on this.

Theres nuthing worse than catching a piece of brush, having the vacume line damaged or detached and losing your 4wd on the trail. If you use the truck for off road I strongly recomemd manual hubs, you might have to get out and lock them (or as i do make the passenger do it) but at least you know it will be there when you need it. Mark There is no vacuum lines on an '87 Chevy for the hubs! > > Hi All, > > [quoted text clipped - 15 lines] > > Mark |
