I got a 1990 Ford F150 with a 9inch rear axle and a dana 44 front axle. Im going back with a 8.8 rear axle because I busted the 9inch. The front has 3.50 gears, and I wanna go in the back with 3.55 Will this work without busting my transfer case?

The front and rear axles will be turning at close but different speeds. This will cause drivetrain bind and will be hard on all your drivetrain parts. You could get away with it if you NEVER used four wheel drive. You might also adjust the tire sizes so the rear tires are taller than the front tires. Just figure out the ratios and select tires that would compensate for the difference. The rear tires should be about 1.4% taller (3.55/3.50=1.0143), since they will be turning slower than the front tires.

you need to have either matching or very close ratio gears in your truck to make the transfer case work properly if you have a lower gear in the back the the front the the transfer case will make the front work harder then the back i think with 3.5 and 3.55 you are close but i thinki would want matching in front and rear

Will not work any difference in gear ratio will cause gear lock up unless only driven on soft surfaces in 4 wheel drive.
