What you write is not inaccurate, but is a significant understatement. Dave corrects the bearing fit in the knuckle by having spray welded, then he ID grinds it back to where it should have been to start with. This make the fit proper and the outer races do not circulate in the knuckle. If your hubs are worn, they get a similar treatment. As the bosses that the disc fastens to are usually not square and true to the centerline of the bearing, he corrects that. If he suspects anything is less than the best, that gets corrected as well.
Unfortunately, GMC designed and specified these coaches for a 15 year and something less than 100K service life. (That was about double of any production RV of the day.) If they had made many of the parts to the specifications Dave uses, we would have many fewer problems.
Here's what I have from Dave.What's the approximate price?
Three important things to remember:
1 - If the parts you are working on go bad, it can go real bad - FAST. (I have not published our whole story yet.)
2 - With the exception of Dave Lenzi, you cannot pay anybody to give as much attention to the work as you will.
3 - (This one is kind of gouche.) Everybody's shop time everywhere is 100$/hr+. This value will cover any tools you need to do the job right.
Matt - here if you need me.
I appreciate it. I accumulated many woodworking tools when my wife and restored our 1959 Shasta. That was a heck of a project, learned a lot, lot of trial and error, mainly with the wood and the framing, panelling, cutting, etc. But paid someone to do the serious work, installing new axle/springs/etc.
Here with the GMC, I am afraid of trial and error for obvious reasons. And it seems no one can work on them here locally in Colorado with much knowledge or experience. Thank goodness for Bruce, but he lives an hour away and is happy to share his experience, not charge me an arm and a leg.
Still, sometimes I feel as if I bit off more than I should have. Not a mechanic, don't have the facility to work on it and maybe its just not right for me. We'll see.
Well, I removed and sent parts to Lenzi, and they are back here now. I will assist Bruce Hart in installing these new parts and pieces from Dave, lower ball joints and new shocks. Should tidy up the front end nicely if it all goes together correctly.Kevin take it from a mechanic with 35 years experience....your doing a fine job . You have the aptitude, your willing to read, follow directions and your not afraid to ask a question so you'll get it fixed. Between the 2 GMC forums their is a ton of knowledge available, not always in agreement of course but hey, everyone has experiences to share that may help.
Don't feel bad, i know your pain.....i don't have a shop either unless you consider a gravel driveway ideal, all my real tools are a 3hr drive away and half the stuff i'm repairing seems like 2 steps forward and one back....but i keep reminding myself that its an adventure and if i had to pay someone to do this stuff i wouldn't have the cool GMC in my driveway. There are days when i question my sanity, then the wife and i will go for a nice drive with usually a to stop at the local RV place, look at a few new units, look at prices. This always makes me smile as i know the GMC in the driveway is 10 times the machine at a tenth of the cost......then i'm good again till something else comes along. Today was test the water system day.....but that's a whole new story... i think i need to go for a drive again .
Carry on my GMC Brother
I love this grease gun!: https://locknlube.com/collections/grease-guns/products/locknlube-pistol-grip-grease-gunWell, I removed and sent parts to Lenzi, and they are back here now.

I need a grease gun. Looks like this may be best bang for the buck:
But I am wondering if there is much difference between them all, since this is something I haven't used in 30 years....Recommendations?
