About to roll this truck off a bridge, it's bad enough you can't have open drinks in the cup holder on the interstate/parkway. 

Angle of the driveshaft since it is lowered? Had a 04 that needed shims to get the right angle, was violent at freeway speeds until they found the right angle.

 

Just a guess.

I put money on this if I had to.

I've had these MRR T228 for 2 months now and have been at the shop 4 times to diagnose a shaky wheel/tire combo at highway speeds. I had Toyo proxes st tires and went thru a combination of 7 different wheels and 7 Toyo's before the shop ordered some Nitto's the same size. The Nitto's were put on and the truck STILL shook so we put the stock 18's on and the truck drives great, NO SHAKE. Any help? MRR is to the point they almost don't wanna help and I'm having to look into new wheels. Anybody went thru the same thing?

Off the original topic, that is a GREAT looking truck, makes me miss my 04, same stance and looks. Victory Red with 20's, matching painted hard tonneau cover.

Thanks, I'm in love with how it looks, i want maybe an inch lower and I'm good. I want a paint matched cover but the price scared me away for a while!

The tonneau I had came with the truck, lots of dealers used to lower or lift trucks, then you just bought it with full warranty.

 

It was PIA when I first bought it, the lowering kit on the truck just did not work as advertised, ending up having to have the back half of the transmission housing replaced (tail shaft area), it would vibrate and bottom out so bad, it cracked.

I finally ended up getting the driveline shimmed (shims under the leaf pack, rotating the axle), replacing the drop shackles with factory ones (just a static drop), and having the wheels rebalanced. After all that, I still had a rough 3-5 drop, never bottomed out, or vibrated again. Could tow and put a normal amount of weight in the bed.

 

Good luck, the problems are hard to find when you alter the factory specs (geometry) of the suspension.

Going to make sure this isn't what they've already done. I know they mentioned shims when they were trying to figure it out.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
