    Suspension overhaul time?

    Every time mine has developed that clunk.... it's been front swaybar bushings or end links. Every time.

    Horrible Fuel Mileage

    Different differential ratios will DEFINITELY affect MPG. It's not necessarily a geometric difference ( the ratio of the ratios ), but it will be affected.

    Horrible Fuel Mileage

    How are your brakes? Dragging breaks can definitely negatively impact fuel mileage. It should be obvious if that's the problem as the brakes themselves will be excessively hot. What differential do you have vs. the one you had in the other vehicle? 12.5 MPG is "bad", but it's only 10% less...

    speaker questions (2)

    Your front speaker test probably sounded as it did because it was not balanced. The amplifier is divided into what I'll call "banks" and channels. The front bank has a left channel and a right channel so does the rear. If the impedance between channels does not match, the bank for some reason...

    speaker questions (2)

    Whether or not you have Bose is usually indicated on the head unit when you turn it on... it will usually say "Bose" on the info display. Bose systems are more sensitive to speaker impedance than non-Bose systems. As for the speakers - as already noted, you can usually fit 6.5" into 6.75" -...

    Snow/Ice Driving Tips for Part-Time AWD 360s

    G80 is what I have as well and I can say one thing.... TIRES. Tires is what will make you go in the snow. Tires is what will help you stop in the snow. The AWD is "good" in my opinion, but it might as well be non-existent if your tires aren't up to the task. I've driven my AWD Bravada through...

    SOLVED! Ride quality after lift and tires

    This is the #1 reason that camber "is not adjustable" on most vehicles.... it shouldn't be adjusted is probably more accurate. They've already accounted for squat/roll/etc... in setting the camber and caster at the factory. That being said, props to you for figuring out how to adjust and for...

    shift points

    Sorry, still not a great comparison. While it is a body on frame vehicle, it still has a curb weight approximately equal to your LaCrosse, about 3400 lbs - THAT's why it behaves very similarly to the LaCrosse. The 305 will have a horspower/torque profile similar to the modern 3800, too. VERY...

    You're comparing apples and watermelons.... Your Buick LaCrosse (you didn't provide a year) could weigh 1000 lbs less than the trailblazer. The thrust-to-weight ratio alone would be 25% better all other things being equal (and they're definitely not equal). Your Buick LaCrosse is front wheel...

    Manic Monday

    Obvious things to check: are any coil packs unplugged? Were any sensors unplugged? Any hoses removed and not replaced? - including the few vacuum lines there are? More troubleshooting: Clean the throttlebody if not recently done. To troubleshoot the misfire specifically: remove air tube to get...

    SOLVED! Ride quality after lift and tires

    So... suspension geometry is half science, half black art. Of primary importance with an alignment is "toe-in"... or more likely in your case "toe-out". It's not unusual for vehicle to be set up with a small amount of "toe-in" - that is to say that the leading/forward edge of the wheels is...

    transmission pan bolts/fuel filter

    Cut or break the fuel filter strap.... use a zip tie to reinstall. If you change your filter on schedule, it won't rust like that. Just my 2 cents.... I had a shop replace my fuel filter as part of another service I had done (an inspection, I think).... bastards charged me $60 to do it... and I...

    19mm Caliper Bracket Removal

    I'm going to ask the stupid question.... are you turning them in the correct direction? I don't think they're "left hand thread" and I don't remember if the heads are accessed from the back or the front, but I do remember they were a huge pain in the butt. Breaker bar for the win... penetrating...

    New tie rod ends

    Try to slip a 15mm wrench over the threads... if it fits, it's 14mm if it doesn't, it's 16mm... I don't have calipers and don't trust my eyes to read mm off a tape.

    Rear ABS sensor

    Remove that screw and spacer and clean them as well.... should be essentially "shiny". That whole mounting surface should be completely free of rust. Be careful not to "plane" it - i.e. don't wear it down. I've used high grit sandpaper and precision files to clean them just don't take away too...

    Longer outer tie rod ends

    It's expensive but not entirely uncommon to replace "ball joints" in lifted rigs with "heim joints". But this is usually reserved for extreme off road and "spared no expense" builds. Using a heim joint and some custom milled / threaded DOM tubing you can do just about anything - including...

    Longer outer tie rod ends

    Is that a cut/crack/split on the outer tie rod boot on the last pic? And +1 for tying up the ABS wire.

    fill/drain plugs for rear ends and TC

    OH, forgot to mention.... if and when you remove the drain or fill plug... CLEAN IT. Use whatever is necessary but it's metal and can take some abuse. I use a stainless bristle brush and brake cleaner... when I'm done it looks almost new. That way there's nothing to gall or gum up the threads...

    fill/drain plugs for rear ends and TC

    one word: contamination.... Never seize is one thing you definitely don't want mixing with TC fluid... probably also don't want it mixed with diff fluid either. My preferred strategy for not letting them get stuck: dip them in the fluid they're for before reinstalling them. Set aside a very...

    heated seat

    ???? Sounds like someone swapped out switch panels. Heated seats are there, or they're not and should be both sides unless someone has "tinkered" with them.

    what if my exhaust manifold is cracked

    MANY crack.... but not necessarily ALL. Investigating exhaust leaks.... SUCKS... and can be very dangerous. That being said, it is certainly doable. With the car running but not necessarily at temp, car in park (obviously) you'll need to get access to the pipe area presumably by laying on the...

    Carbon Busting with Berryman's ChemDip: "The Proof is in The Pudding"

    I have used this same exact product many times.... to dissolve gum/varnish/carbon on/in carburetor parts including jets, floats, bowls, crossovers, etc... Its reusability when utilized for that purpose is legendary.

    Longer outer tie rod ends

    I've not done the flip and wouldn't be certain how to tell. I don't know if the UCA is "square" - meaning the UBJ is in the center, but if it's not then it could throw some angles off. This is area is def not my strong suit, the side-swap was just something I question as an observation. It is...

    Reading the transmission dipstick

    In addition to the transmission needing to be "at temp" and the engine runnning, I've always placed the transmission into every gear before reading fluid level. I usually put it in Reverse, then 1st, 2nd, Drive, Neutral and Park. Then check the fluid. I don't know if that changes anything. Also...

    Longer outer tie rod ends

    Was the UCA flip done correctly? Aren't they supposed to be put on opposite sides if flipped? Was that done?
