my god mothers neighboor gave me a 91 maroon bravada this summer and i drove it all the way back from whidbey island washington.
230,000 miles, but when i give it a little tlc and a full tank it hauls ass.
big problems with suspension, last night i heard a loud pop near fornt right of car, could hae been a poping tire sound but nope tire ok, i think it was in the suspension somewhere.
next the key got so worn down i had the great idea of pulling the ignition. so now it starts with a screwdriver and is all mangeld.
door is bent or something so i have to really slam hard a few times to get a week seal.
a/c doesnt work and all settings for direction go one way.

As far as the suspension goes I would recommend going to strutmasters.com and taking a look at the conversion kits. This is a permanent fix unlike air which will always have problems. The conversion kit converts you from air to powder coated, American made steel coil springs that are guaranteed to last the life of the car. I posted the link below so you can take a look.

Hopefully this will help with atleast one of your problems.

Good LucK!!!
