Only real problem we had with our dodge(the truck itself) was when a wheelbearing went out and screwed with the abs tone ring we lost all brakes. Other than that I've had more problems with my duramax. Dodge trucks seem to be just as stong as anyother truck IMO.

Wheel bearings, pitman and idlers, rear axle gasket, leaking trans lines, blowing intake orings, heater hose hole, mystery coolant leaks, cruise control not working right, half my dash gauges die, horn doesn't work sometimes, hard trans downshifts, 4x4 doesn't engage right away, differential stays locked sometimes, and a bunch of codes. I'm sure theres more

Most of your coolant leaks were from your egr delete and also your egr delete was blowing the o rings so that's not the trucks fault. The trans you pushed were hard and ran it well past needing rebuilt so I could see you having issues with it along with some of the wiring you have done to try and get lock up before the built trans with grounding out the switchs.

Yes the wheel bearings go out sometimes with oversized tires. I lost one on the driver side from running a 285/75/16 with a wheel that was set way out on the front a made it wear more. I'm just getting ready to turn 70,000 miles on my truck still factory tie rods and indler and pitman arms. From about 3,000 miles I added a center link and sleeves and idler and pitman arm braces. I have not been easy on my trucks front end at all with all the 4 wd boosted launchs. If you install some extra parts they hold up for what your wanting it to do.

But not with the delete. I have had other coolant leaks too and also your egr delete was blowing the o rings so that's not the trucks fault. Yes that is true, but it was GMs shitty design on the pressed seal intake horn that allows for it. The trans you pushed were hard and ran it well past needing rebuilt so I could see you having issues with it along with some of the wiring you have done to try and get lock up before the built trans with grounding out the switchs. Many people have ran manually grounded switches
Yes the wheel bearings go out sometimes with oversized tires. They are junk and pretty much are garunteed to fail, even on stock tires. I run 285/65/18s and while that is not huge I guess it is "oversized" since GM puts the smallest tires possible on these trucks from the factory. If you install some extra parts they hold up for what your wanting it to do. Yeah once I get these worn pitmans and idlers fixed I am adding a 1.5inch straight CL. And cognito style braces, IF I still need them running a straight link?

One of you posts said you had a coolant hose with a pin hole in it that was after the egr delete never saw you post of the egr eating coolant before. The stock neck with o rings works fine stock and also if the braves are good and strong. My stock kneck never had a issue I modded it after swapping the Gt4094 to the Gt42 and made a egr delete on mine and added the tab and bolt to help hold it. Not sure why some have so much trouble getting the neck back in to the bridge it pops right in. Think the offset on the rims that some of us run help wear the wheel bearings the gunner 8's I was running set out alot.

One of you posts said you had a coolant hose with a pin hole in it that was after the egr delete I did have a small pinhole. It was on that prebent 45* hose... I think the 2 metal nipples the hose slides over just binded up the hose too much.. I installed the egr delete about a week later iirc never saw you post of the egr eating coolant before. I still am not sure if that was the case. but am still leaning towards that. It stopped eating/disappearing after I rid of the egr. The stock neck with o rings works fine stock and also if the braves are good and strong. That is very true. but with a delete pipe I have only so many places to brace it to with what it is. My stock kneck never had a issue I modded it after swapping the Gt4094 to the Gt42 and made a egr delete on mine and added the tab and bolt to help hold it. Not sure why some have so much trouble getting the neck back in to the bridge it pops right in. Think the offset on the rims that some of us run help wear the wheel bearings the gunner 8's I was running set out alot. Yeah I would say that would be more of a problem than tread width, I'm not doubting that thread width hurts the bearings but offset kills it

I have been running 35" tires on like -20 something offset and haven't had any problems with my wheel bearing. Maybe I'm just lucky.

I dunno why half the people post in this thread? There are lots of threads I've seen that I don't give a shit about ..... If you don't have constructive advice stay out?



I'm not always one to talk but if we want a good forum we have to expect questions like this.let's make a place that you can ask anything and NOT be bashed! That is why I first came to this site.:(

I don't care what anyone says between me and dad we have owned them all, and I can tell you hands down the duramax has by far had the least problems, LB7 has had injector issues 5 times but 3 times was dealer's install issues. The LBZ has never been in the shop only issue is a small tranny line drip in the winter.

The only trucks that were as reliable as the Duramax's were the 7.3 idi and 7.3 powerstrokes minus a couple tranny issue on the E40D's they were stout as hell. Our 6.0 powerstroke lived in the shop, egr (4times), injectors, tranny, transfer,
all in the forst 100K

The cummins were awsome motors no doubt, but damn thed trucks are pure garbage. Tranny issues wheel bearing, hubs, deferentials, deathwobble, interior crap... etc But all the trucks made it past 100K before any real issues.
