Question about 1994 Ford F350 Crew Cab

2 Answers

4 wheel drive (auto locking hubs) seems to be trying to engage.

I have a 94 F350 4x4 Crew 7.3 Diesel with auto locking front hubs. i am hearing a clicking noise like the hubs are trying to engage. as i slow down to around 15mph, there is a loud clunk from the front end. the front drive shaft does not appear to be engaging, just the front hubs. there must be some time of engaging mechanism actuated by air or hydraulic pressure. any help?

I had the same thing happen. The automatic locking hubs are faulty, causing one or both hubs to try to engage or disengage onto the front driveshaft. This makes the clicking noise and loud clunking that you hear. You may notice your steering pulling to one side of the road,because one hub is locked in. Replace the automatic hubs with new ones, do not try to fix the old ones. I liked the
convience of automatic hubs but replaced mine with manual hubs, there just way more reliable.

Does yours have AUTO hubs, there are some luxory models have auto hubs, these rely on difference in drive on the axles,(wheel spin) others have manual locking hubs, these actually need to be engaged manually, these require you to twist the centre of the hub to engage and disengage the front hubs, these sometimes require you to reverse to disengage properly, Rodeo had both depending on model.

I had a 4 wheel drive suburban..it had issues with the high-lock and low-lock..I just used the auto setting because all four wheels were getting power anyway..only time you need lock is when you plan to go bogging in really deep mud..on snow/ice all you need is all wheel drive..you actually have better control..as long as it works in all wheel you should be fine..also be checking the front hubs.. are yours full time or do you have lock outs..on the axle hubs..thats my question

Front drive shaft not fully engaged in 4WD, with truck on stands all 4 wheels do rotate but if i stop front wheels the front drive shaft is not engaged


Hi,
Do you have auto locking hubs on the front wheels, or manual locking hubs?
If you have auto locking hubs chances are they are not engaging properly and will need to be removed and spline sets checked for broken teeth on locking hub and locking shaft.
If you have manual locking hubs then check that they are firm when turning to engage them in the lock position.If they are light when engaging them to the lock position then they my have broken/worn out the locking hub and spline. Also check that the engaging spring inside the hub has enough tension to engage the hubs they may be broken. If the hub are all ok then you have a problem in the transfer box, where the 4WD lever is not meshing the transfer box properly. Hope this helps, let me know how you get on.

I have a 94 s10 4x4 when i put it in 4wd u can hear it clunk clunk trying to engage but front wheels wont pull


? are they manual locking hubs where you have to get out and lock them? if not you may have a vacuum leak to your actuaters .my spelling is terrible.another ? is the clunking sound only when you put in 4wheel or is it in 2 wheel also.if so you also may have a bad universal joint either in the front drive axle or the rear drive axle.

Ford 250 auto/lock hubs


I have the same hubs on my truck as what you have. I have been told it can be done you just have to know if you have a dana 50 or 60 front axle. The warn hubs i'm sure are a better quality hub but if your worried about the auto feature of your current hubs. That is vacuum accuated when you 4 wheel drive is engaged. And there fore vacuum engaged. Mine used to work great but after a lot of mudding sand got into seals and vacuum didn't work anymore so i treat them as free/lock hubs.
