Grinding sounds after you've had new gears and CV joints installed in NEVER a good sign. Grinding coming from the outer knuckle could be from something as simple as lack of grease on the brass spindle bushing. But grinding noises, and lots of heat coming from both center pumpkins is a sign something was not installed correctly or a low gear lube level, or no gear lube at all. My advice, DON'T drive your truck 100 miles down to his shop to have it looked at. Because if you do, your going to run the chance of causing even more damage then what may of already occurred. Have it towed there, If they are a stand up shop, they should cover the cost of towing.I assume grinding is NOT a good thing ?
Yeah I just called the shop and he said they'd stand by anything they did , and to have it flatbed-ed down to them . I had a friend check the driveshafts and there is zero up and down movement ... I did drive there ( 5 miles ) and there is only a slight hum. after he verified the driveshafts don't have slop, we took it down hwy 49 up to 70 mph ... no sound other than a hum, that we assume is just brand new gears shaving off material. Ofcourse it wouldn't make the sound while someone else was listening. Anyway , I know your think I could have checked the drivelines my self .... I fell 5 months ago and ripped my right quadracep and 2 top tendons completely off my knee... so getting under anything is a little hard right now . Anyway , The shop guy said he'd pay my friend a hrs worth of labor to run the truck on 4 jack stands to see if the sound would happen and if it was more of the same , he said that he'd pay to have it towed down... and then they'd get back up to me when finished ... he is a stand up guy ! So fingers crossed ...
oh I should say to that that they rebuilt the knuckles as well ... so I assume theres grease where it needs to be ...
This was done at a very reputable Land cruiser shop... that alot of folks here know , so I'll just leave it at that ... no need calling anyone out if they can make it right !
Just as an FYI, i use to run Gleason Gear generators, that's the machine that machines the teeth on both the ring gear, and the pinion gear. If your ring and pinion gears are set up property, then VERY little material will be worn off the teeth during break in. Plus you'll have no noise or hum coming from your gear set while running.no sound other than a hum, that we assume is just brand new gears shaving off material.
Don't count on it, In all the years I've worked on cars I've seen shops make some really bone headed mistakes. I once saw a transmission shop rebuild a manual transmission, then they forgot to fill it with fluid before they delivered it to the customer. So don't think s*** like forgetting to put grease in your knuckles can't happen.I had the knuckles rebuilt , so I'd think they'd remember to install new grease.
