Dodge Ram 1 ton with a noisy front differential. How to Properly repair and replace bearings

[@hodwooker5584]

If you cannot get a job with someone like Dave. Get some education, trade school. If that isn’t possible. Get a job with someone, somewhere, somehow, doing work in your chosen career. That way you can get experience in the job. Then listen,learn, even if it is not the best shop you can learn something. Hang in there a year maybe two. You don’t want to look like you can’t hold a, job thats not a good thing. Then the Daves are going to look at you different. Be honest tell the interviewer what you want from the job, have that in mind before the interview. Good jobs are hard to find. You have to work hard at finding a good job. Then you need to work hard to keep it. This is advice from a 72 year old retired electrician for a young person. But it will still apply to a job seeker in skilled trades. One of the great mistakes our country has made is to stop using trade schools and apprenticeships. Good luck to you!

Good teaching/coaching techniques.

Another great video Dave. Back here in the UK July 1972 I was just starting my apprenticeship as a mechanic with a Ford main Dealer in Enfield North London. In 1970 Ford UK had launched its latest model - the Cortina MKIII but by late 1972 these vehicles where suffering with increased rear axle noise levels. On the TSB's it was referred to as "axle howl"! These axles were know as the Salisbury axle and is much the same as the one in your excellent video. For the next 18 months plus we were inundated with dozens of axle rebuilds every month and all under Fords warranty. Watching your video takes me right back to those very hazy days where we could rebuild a Salisbury axle almost blindfolded. Pre load, backlash and collapsible spacers are all so familiar!

I learn everything about the hydraulic systems and how to change them, welding etc. On all the gasoline fleet trucks and pick-up trucks the same. He said same a you, service any equipment in half of the time suggested by the manufacturer. 43 years later I do the same in our cars. You work is one of the best I have seen. Quality over pennies.

This is awesome to seen Dave teaching this young man, he’s direct but patient and makes sure his student is taking in the wisdom Dave is blessing him with.

I'm a mechanic here in Brazil, Rio de Janeiro. I'm watching your videos. Costumers you know, they are crazy, but seems that Americans are a little different, looks like they are not used to maintain their cars. It's harder and harder to get cars here that the owner don't change oil or let parts broke to the point that's get worse than fix the primary problem. For example people don't complain to fix or lie about leaks like old times. Well I wish you best. you are a very honorable man and have my honour.all the best things for you and your family.

Your apprentice looks like my cousin Mark. This video grabbed my attention, in August of 2000, I was driving my recently serviced from a new shop pickup truck towing a 35ft 5TH wheel brand new camper, with me were my 2 sons, aged 5 and 9, as we exited off the Massachusetts Turnpike to exit 490 I suddenly felt my rear of the truck drop down, as I looked both of my tires and axels were beyond the truck bed box, I immediately pulled over and as I put my truck into gear and opened my door to exit and inspect, my truck rolled, I only had front breaks and trailer electric breaks. Thank god a prison van stopped along side of me on this extremely narrow exit ramp, I begged him to place a boulder in front of my front tire as we were on an exit ramp w a 5% downward grade. Long story short the state police said if that repair shop was in Massachusetts as opposed to Connecticut he’d arrest the shop owner. 16 hours later a lowboy showed up and towed us home, a ruined month vacation, a 10 hour drive, We were headed to Canada as I’ve done for 20 years before that. The diagnosis was a pinion nut that the shop owner forgot to torque. He acknowledged such. That was 24 years ago and I still won’t take that exit. Thanks for a detailed video on the pinion, thanks Ron Obtw, you are an excellent teacher, calm, great explanation, awesome job.

Dave you bring back memories of first year motor mechanic 1970 who had the privilege of having the guidance and knowledge of 2 senior mechanics Bill and Ernie. Best time of my working life. I am in retirement now. Love watching you

[@kentharding5874]

I really like the honesty in your work and teaching methods. I've been a motorcycle technician for 25 years and had my fair share of senior technicians teaching me and as the years passed by, my share of apprentices I've had to teach. It's not easy in either scenario. Great job on watching you language. My father was an automotive tech, I was always in the shop with him. My mom used to show pictures of my diaper being changed on a shop bench at a Toyota dealership. Very embarrassing at the time, proud of it now. One day I got dad in sheep dip when my Mom overheard me cussing. Where on earth did you learn those terrible words? At the shop with Dad.... Thank you for the great videos!

[@simpson3048]

bravo Dave ! Dave correctly explained the same principles of tools, procedures to achieve proper preload, run-out, and back-lash. Dave just did what a lower unit on an outboard (boat) motor has. Amazing stuff, Dave!

[@kenhoyle4344]

Great job Dave. Just a home mechanic that knows his limits. Fascinated by the amount of detail in your videos. Makes you feel like Im right there with you learning from a master.
