Guys, alot of these OEM parts that came on our trucks are made in the same plants that make Ford and GM parts. IMHO, several factors are contributing to the increased failure rate. The first of which would be that most of these parts are being manufactured outside of the United States. Whether it be China, India, Mexico... etc. . It really doesnt matter. Its a numbers game much like many other industries these days. Typically the mindset is ," Well, we can manufacture twice as many overseas for the same price as US built parts, who cares if 10% of them fail!!" These parts are inferior in quality of the steel used to build them, and most of the time, dimensional tolerances are loose (I blame the english/metric conversion)
Although we cannot control where the manufacturer buys parts from, we CAN solve MANY of these issues buy purchasing proven/quality parts. Yes, they are more expensive, but will typically give better service and last longer. I remember rebuilding the manual hubs on my 89 CTD with 300K, I actually pulled the shafts, but there was NO wear in the Spicer U-joints... And that truck was ALWAYS being abused.
Secondly, the trucks are getting more and more power that is creating more load on parts, yet we have moved from rebuildable and servicable parts, to disposable diapers!!!! What little grease that is installed at the overseas factory will typically be sheared away leaving little to no lubrication. Now, with no grease zerk to replace it... We have another failing part.
I think all of us that have a 3rd gen 4x4 have the sticker under the hood that mandates that we grease the zerk in the half shaft..... I learned early on that the dealerships were NO help and merely there to sell parts. When my truck was new, I asked the local dealership "Master Technician" about the proper grease gun attachment and was stunned by the answer... "Oh you dont use a grease gun on it, you just spray it with spray grease from an aerosol can. " I explained that his thought process would only grease the underside of the body once I drove down the road, and he assured me he was right!!!. .
Its not just Dodge, our GM and Ford service trucks have had multitudes of front end parts changed. What we DID learn thru trial and error was that the local independent 4x4 and off-road shops carry quality built, US made parts that stand up to the abuses of serious offroad use...
I'm just waiting for the u-joints on my truck to fail. I know they will soon just by the number of threads on low hour failures on the 3rd gens. When they do, I will install quality, US made greasable parts back in their places. If I were to run down to Autozone, Orileys. . etc. . and shop by price, should I then expect the new part to last any longer than the OEM part???. . Chances are, if they didnt come from the same factory, they were made from the same mold prints!!.
ok. . i'll quit ranting. .
