 Topic: Ford ranger 4 wheel drive
Posted: 25 Jan 2022 at 7:50am |
|
Yesterday's victim was a 1999 Ford ranger 4x4 4.0. Liter. Customer said 4 when drive doesn't work. Put it on the hoist and he was right. Everything up to the front hubs work though, so that was a relief. Found the vacuum hoses at the wheels to be rotten. Fixed that. Long story short I found the vacuum valve it does have vacuum to it. I took a hose from there to each wheel directly. Neither hub works at all. So he would have 2 bad vacuum hubs. I see where you can trade them out for the old mechanical lock in style. Have any of you guys done this

I had an older mechanic friend that had a shop in his back yard. He knew how to do what you are talking about. We did that on a 96 F-150 full sized 4 wheel drive. Not as convenient as the electronics but in my book a lot less to go wrong and 4 wheel drive worked and was a cheaper fix

BEST hubs I ever had on any 4x4 were Warn 'lock-o-matic' on my '57 Willys pickup. When Warn couldn't repair them, they sent me a set of 'regular' hubs for free. I'm wondering is water/ice got into the vacuum hubs ??

The RAnger in the 1997- 2001 era used a vacuum system outboard on the hub. They can be removed and replaced with a MANUAL lock as Bob said.. I have not done that.
On the F150, prior to 1998 i think you can do something similar as above.
From 1998- 2003 the F150 had the front axles LOCKED to the hubs.. There is a vacuum engagement at the differential to lock the axle to the driveshaft.. You could use a PULL / PUSH cable to do this.. I have not seen a "KIT".
After 2004 the F150 used an INTERNAL vacuum piston on each front wheel.. No access from the outside.. It is on the BACKSIDE of the hub by the brake disk. Problems with it is the seals and o-rings get hard / stuck due to water / salt / crud ... The have to be disassembled and all rubbers replaced, or just replace the entire assemble.. I dont know of any "kit" to replace the vacuum with manual.

Isn't it ironic that the way to fix this new technology is to remove the new-fangled contraptions and replace them with tried and true components. We'd all be better off if the automakers would fire all of the engineers that justify their existence by designing stuff so complicated that it breaks down and can't be repaired, just replaced. Why do you think a P/U cost 10+ times or more than what they used to. For the most part all the gimmicks and gadgets on new vehicles are not needed.

If it was fun to pull in LOW gear, I could have a John Deere.

The truck he is working on is 23 years old.... Even with the old LOCKING HUBS, you had to do some maintenace... I remember pulling them apart to clean and regrease ever so often. ......... ONE rebuild in 23 years is not too bad.

People don't want to have to get out of their truck to engage the hubs...
