I recently bought a nice used AR-15 with a 9mm upper. I was surprised how hard it recoils when fired with regular 9mm commercial ammo! ARs in 9mm are blow back only so I figured it should have a stiffer spring, but I found no information on that. In the meantime I'm making light 9 mm hand...

Hi all! Running down some weird steering noise, shudder, clunking & shimmy in low speed 90 degree turns only. How sensitive are late model GM FWD racks to Power Steering Fluid exchanges or lack thereof? The book shows it to be messy and awkward. Last year I just sucked out the pump and...

Finally a decent BBQ this summer after lots of weekends with hotdogs and so-so burgers! Also found after years of BBQing, that no matter how big a round plate is, there's never enough room for all the food and crowding your meal! So I looked for the largest oval or rectangular plate I could...

SONNAX has a new Extended Length Forward Band Servo Pin Kit that helps reduce shudder and pounding on the forward band that can result in a broken band and no forward gears! I was under the ‘09 Impala 3.5V6 to do an oil change and wanted to see if I could eye-ball for location and clearance to...

I wonder how many people had experienced drilled / slotted brake rotors that begin to make noise or pulsate badly after just 1 or 2 years? "Extreme Stop" brake rotors are drilled and slotted and are beautiful to look at, but just under 2 years they started pulsing badly when stopping from hiway...

Hi All, If GM made a full size electric car (or gas/electric) the size of a Chevy Impala, I'd buy it. After all, there's enough room for the guts! Chevy Volt too small. One proviso: no crummy GM transmission pls!! Comments?

Hi all, I noticed the aftermarket tranny filter for my 4T65E tranny did not seat all the way into the tranny and looked a little off, I noticed that a metal edge of the filter was hanging up against the inside of the tranny, so I took it out and bent over the metal edge til it cleared. May not...

Hi all, I got a GM 4T65E transmission in a '09 Impala with a 3.5L V6. Just did a OBDII scan for tranny codes since 4T65Es have an awful history. It comes up U0101 "lost communication with TCM " this means I can't see what's happening in the tranny. This could mean wiring / connector problems...

Hi all, Anyone have leads on upgrade replacement windshield washer pumps on GMs that don't break? Winter's coming up here soon! Looking at replacing again on a 2009 Chev Impala 3.5L V6. They're hard to get at too. Last one replaced by dealer for $235 just 18 months ago! In the past I drove...

Hi All I was viewing Pat Goss videos on YouTube and found some claims that looked a little odd. Also come across a PDF called "Bogus Coolant Test - Pat Goss Blows It!" I tried the DMM test with engine coolant and found it's true, this test responds to coolant mix ratios and does not tell if...

Hi all! Last fall the wife got her flat tire serviced while I was away. When I got back I thought I'd put the winter tires on. Surprise! I couldn't get the lug nuts off! I had to pull out a 3 foot breaker bar and lean on it til they loosened! The Shop said they always use color coded Torque...

Hi all, Found a handy summary of auto oil filters and cut-aways by Russ W. Knize. He cut them open the hard way, with a lathe. He did 20 plus brand plus his comments. I guess oil filter cutter tools wasn't available to him. However, I'm interested since I drive my cars forever with really...
