Hey guys. I've been off-line for a bit trying to get caught up on various projects and side work that I have had promised out for way too long.
Last year really kicked my ass when I had my small medical issue and it really put me behind. I had so much work promised out and I am only now, a year later, finally caught up on side work. While I am flattered that most of the people I do work for trust me exclusively, it presents a problem when there is a hiccup to my schedule. I was hoping some would cancel and take the work elsewhere which would allow me to get caught up, but none did. I guess I should look at that as a good thing though.
I thought I'd give a quick recap of some of the work over the past couple of months. Last I left off with was I think the Jeep Wrangler JK that I did some repair to the bracketry for the front track bar.
After that I had a 2010 GM in the shop doing some diagnosing which turned out not to be good news for the owner.
After the GM truck and with the weather getting nice the wife and I wanted to put some miles on our Camaro that we have had about a year now and haven't really had time to enjoy it. I noticed on one of our Sunday drives that the A/C was not performing as desired so I threw the gauges on it and found it was a little low. I was unable to detect a leak anywhere so I put a few ounces of refrigerant in it and I'll keep an eye on the system.
It was also due for a full LOF service so I racked the Camaro and changed the engine oil and filter.
Then thought I'd address the rear end howl. I have been using Valvoline Synthetic gear oil with the friction modifier in it for nearly 20 years now with excellent results. Never an issue, until this Fifth Gen Camaro. After servicing the rear end last fall I immediately picked up a rear end growl on tight turns at slow speeds when cold. It seemed to get a little better once warmed but it drove me up a freakin' wall. I hate it when my own vehicles have an issue and I am not able to immediately get to them. Maybe that's why I didn't put that many miles on the Camaro in nearly the year we've owned it.
I had done a lot of reading and several forums mentioned that people were experiencing similar issues if not running the OEM GM gear oil with the friction modifier. I wasn't sure I believed it because my history with the Valvoline fluids had been so flawless that it must have been something coming apart in the differential clutches. I thought I'd dump the Valvoline and give the GM fluid a try.
The new GM fluid also has the correct friction modifier, same as Valvoline lists.
Also while I had the car on the rack I figured I'd flush the cooling system and put all fresh coolant in the car.
After a few test drives the car is performing flawlessly and lo and behold the gear noise was gone almost instantly. I'll be damned. If I hadn't experienced it I don't think I would have believed it. I actually didn't believe it at first that is why I was hesitant to just dump the Valvoline and go with the GM fluid.
The wife and I have now logged about a thousand miles on the car in the past few weeks on several drives and it is a joy to drive.
In between side jobs I have been able to get a few tasks on our own vehicles completed but my goal was to get caught up so the wife and I could enjoy our few RV'ing and Jeeping trips this summer.
