2003 2Dr Blazer Zr2 4WD - was driving along tonight, hit a pothole and heard a loud bang. Almost thought I had blown a tire. Turns out the torsion bar mount crossmember had full on split in half, dropping the front end until the tires and wheel wells are almost kissing. Any known sources of replacements or am I pretty much stuck with praying there's one at a PickAPart within Uber distance?

 

I would call around to local salvage yards to see if they have one. That is not a common part to fail, so I guarantee someone will have it. If you don't have a ride, you may be able to ask them if they would deliver it to you house for a fee. They will usually only deliver to businesses, but someone my be nice enough to help you out if you explain your situation.

Car-Part.com is a good place to check local salvage yards. I don't know if all torsion bar mounts are the same, but just search for something unique to the 2 door ZR2 4x4 such as the rear driveshaft and if you search by distance, it should show you local yard with ZR2s

 

Best bet as mentioned above, plus post in the wanted section on here. Second bet would be to have one fabricated. This should be to hard for a decent shop. Third, and I don't recommend this one in the least, weld the damaged one back together.

 

Yeah I live in a coastal area prone to tidal flooding, so rust issues are a constant nightmare. Just weakened so much from rot that it finally snapped. I havent had the greatest luck with salvage searches, but luckily was able to get a new one ordered from GM Parts Headquarters.

. . . . . aaaaaand I spoke too soon. They didn't have it after all. Back to the drawing board.
