To change the rear main seal on a 1990 Bronco, first, you'll need to remove the transmission and flywheel or flexplate to access the rear of the engine. Next, carefully remove the old seal using a seal puller or a similar tool, making sure not to damage the crankshaft. Clean the area thoroughly, then lubricate the new seal with engine oil and press it into place, ensuring it sits evenly. Finally, reassemble the transmission and other components in reverse order, and check for leaks.
