I replaced what ever axle comes stock in my custom with trail boss axles. Part number 84554912. Removed axle nut separated bottom ball joint and popped axle out of diff. Wasn’t bad, the dealer showed me why the quote was so high and it was because book says to pretty much disassemble the complete suspension on the given side.
I ended up replacing mine with part number 84554912. The axle itself isn’t longer the inner tulip is and allows more travel of the CV. I haven’t had any issues after installing these axles. Be careful where you have them installed also, I was quoted labor as 3 hours per side from gm and an Indy shop. Ended up doing it myself 45 minutes per side.
The outer CV and boot on both sides. I think it’s luck of the draw.. a friend had the 2.5” lift also and had no axle issues... only difference is his trucks a pavement princess not that I off-road mine but I do drive it on the beach and now that I think of it that’s when my axle issues started.
Definitely not an installation error, think it was just to much angle at 2.5” for the axles. When I replaced the axles I used axles from a trailboss. Axles measure the same length but the inner tulips was about 1.5” longer.
Hi, I had the 2.5” motofab leveling kit on my Silverado crew cab. I put about 2K miles on the truck with that leveling kit before I killed the front axles. I removed the kit and went down to a 2” motofab kit and replaced the axles. Have been very happy so far. I also raised the rear 1” as I tow a bit.
I installed my compustar myself, only tapped the parking light wire as well. My opinion is the Tharness makes it alittle harder for the thieves to delete the alarm. Hide the alarm brain well and the harnesses all look the same, where as when an alarm is hard wired you can see the points to just rip the wire off.
I actually ended up changing the spacer out today to a 2” top Mount spacer. With the truck up on the lift and closer inspection it looks like at certain angles the pinch on the Clamp for the cv boot would rub the bottom of the strut mount with the 2.5” spaced down there. I know it’s only a half inch difference but the axles and ball joints look happier now.
Hi, New to the forums but have been a lurking for quite some time. Today i ran into my first real issue with my truck. I have a 19 1500 custom with a motofab 2.5" level kit. Put aprox 1,000 miles on the truck since the install and now today as i changed my oil i found grease coming from both front axles. I inspected the axle boots and cant find any tears, it looks like its leaking past the clamp on each axle. Has anyone else had this problem? Would there be any advantage to replacing the axles with trailboss axles to compensate for the lift? Thanks for any advise that could be given.
