2002 Lexus LS430, 45,000 miles.....Another auction rat belong to a car lot. With the mileage I'm guessing it sat quite a bit, Complaint of low power & A/C doesn't cool.
Knock sensor circuit DTC's in the PCM & Compressor displacement Solenoid circuit DTC, Soon as I opened the hood I caught the pungent aroma of Mice/Rat feces & urine simmering over a hot engine
Knew right away to pull the intake & sure enough both knock sensor circuits were chewed in two, Along with the intake runner vacuum actuator solenoid circuits chewed in two.
Fixed that & installed the intake, Onto the A/C issue.....
New compressor has been installed, Pulled the lid off the PCM box to access the inline connector that has the Compressor Solenoid circuits in it, No power from the A/C ECU, Applied power the solenoid & could hear the compressor start to pump but no cold air.
Threw my gauges on & it was way low on refrigerant probably cause they couldn't get it charged without the compressor pumping.
Vacuumed & charged the system.
Got it too cool but the head pressure shot up & the Condenser Fan didn't come on, Had power & ground to the fan, Smacked the motor with a pry bar & it went to work.
Found the Compressor Solenoid power circuit chewed in two under left front fuse/relay box along with another circuit, Not sure what it did but I repaired it.
Car lot declined a new Condenser Fan Motor
Charged an extra 2 hours for dealing with the rodent waste, Threw the filter to my shop vac away & cleaned the tub out with soap & water as I'm very sensitive to that smell & to be honest it gives me the heebie-jeebies!
Building a 9" Ford differential for my dads '72 Olds Cutlass with a '17 6.2L LT1/8L90E.
Has a BOP 8.2" in it now with 3.73 gears. With relatively short 26" tires & the 8L90E's 4.56 1st gear ratio.....It will boil the rear tires off at will & the TCM likes to freak out & either shift way to early or too late.
2 series posi carriers for 8.2" BOP diffs are impossible to find used & no one makes a new one, While it's stronger than a GM Corporate 8.2".....It's still on the weak side.
My dad is a Ford hater through & through, So I recommended a Corporate 12-Bolt as used 2.73 gears a readily, But a 2 series Posi Carrier.....Not so much.
I finally beat him down by talking smack every other day about how the Ford 9" has no carrier breaks & the ONLY stronger differential put in passenger cars was a Dana 60 & the highest ratio available for them was a 3.07 which are also near impossible to find
.
Found a complete 9" differential out of a 1979 Lincoln Versailles with factory disc brakes & 2.47 gears. Having Quick Performance build a new housing to fit this A-Body & supply some 31 Spline Axles.
*Yukon 31 Spline Trac-Loc posi carrier.
*Strange Daytona Pinion Support.
*Couldn't find a kit with Daytona Pinion Bearings & seal along with 2.892" carrier bearings, So I bought a kit with 3.250" carrier bearings & have 2.892" bearings ordered.
*Yukon 1310 Yoke.
*Yukon Crush Sleeve Eliminator.
I tried checking the Pinion Depth before removing the Pinion & Support cause I really want to get these gear right back where the were as the pattern is perfect. If I was reusing the original small bearing Pinion Support.....I could reuse the factory shim with confidence.
Must of got 14 different depth measurements before I caught on that the end of pinion was not flat (Not even close)
Chucked the Pinion on my lathe & trued up the pinion end.....Reassembled the pinion back into the original support & was able to get a repeatable depth measurement.
In my defense.....I'm used to aftermarket gears with machined pinion ends & the recommended depth stenciled on the pinion.
I got the Pinion & Support fully assembled with near perfect bearing preload which takes some time shimming .002" at a time.
Got further along on the 9" Ford build for my dad's Cutlass......
Had to clearance the case a bit to clear the Posi Carrier, Not uncommon with aftermarket carriers (Arrow)
Had to add .002" of shim to get the Pinion Depth back where it was.....Meaning the Strange Daytona Pinion Support is machined VERY WELL.
Backlash was .016" originally (Gears already broke-in), Got it too .015" & called it good.
Ran a pattern & looked really good.....Right back where it was.
Spent 45 minutes cleaning inside the housing of grinding debris, Installed 2 GM Transmission Magnets in the bottom of the housing & in has a magnetic drain plug as well.
Lube-Locker Gasket, 10 new Copper Crush Washers, And new grade 8 Ny-Loc Nuts.
The company that sold me the Axle & Housing package failed to heed my request to leave the wheel bearing off the Axles, I have to install the disc brake backing plates before pressing the bearings on. So they will get a call on Monday along with a tongue lashing as I made it VERY CLEAR more than once while ordering to NOT press the wheel bearings on. And I warned the guy I'd be upset!
