I noticed that the front of my '04 Silverado 1500 (4.8L, 2WD, Reg. Cab, 8 ft. Bed, with 98,000 miles) looked a bit tilted. So, I took a body height measurement as follows: * using the center of the wheel hubs as my common point of reference, and a dry-waller's T-square... I measured from the ground to the fender/wheel opening * the Driver side actually does sit about ONE INCH lower than the Passenger side After doing some research online, I find this may NOT be an uncommon situation... and after talking to some friends, I'm thinking that the front COIL SPRINGS are likely the culprit? My ALLDATADIY.COM reference tells me that the coil spring's OEM Part Number is 15760837. I did some looking around, online, for replacement springs, and it seems that there are COIL SPRINGS being sold which address this situation. For example, on this website, they show that the MOOG part number 60150 is an alternative which is "FOR USE IF DRIVER SIDE LEANS DOWN 1/2" - 1" LOWER THAN PASSENGER SIDE". :grrrrrr: Rather than spending a ridiculous amount of money to have someone replace a coil spring for me (as I don't have a good spring compressor and would have to BUY one in addition to the cost of the coil spring)... I thought I might just use SPACERS to lift that coil spring by about an inch. The coil spring itself is about 7/8ths of an inch in diameter... and that means I can't use something like a 18-1201A Spring Lox, because there's not enough space between its bolts. I was also considering the use of these Twist-in 18-8001 or 18-9001 ... but I hesitate to do so, because the "spacing on the coil" is not UNIFORM all the way around (i.e., the outer-side is spaced further apart than is the inner side). So, my question is... Have any of you encountered and CHEAPLY corrected such a problem (FRONT driver-side sits lower than passenger-side)... and if so... care to share your secret? Thanks, in advance.
