I looked at 19 Rangers last week hoping to find a decent LS rear axel. No such luck.
Their fate was rather sad: rode hard and put up wet, and done so year after year, treated roughly, never loved, never accessorized, had no special factory options, were never garaged, or even waxed, rusting out everywhere. Almost all suffered their fair share of dents and dings. One was hail damaged and never fixed. The cabs were greasy and smelly on the inside: the carpets were caked with dirt. The dashboards were scuffed and scratched, seats stained, many with cigarette holes. many never cleaned or covered. Even the headliners were messed.
I found a few potential limited slip donors only to find one axel was rusted beyond saving. Another had a leaky differential, not at all a good sign.
Perhaps too, these little boneyard trucks tell another story: that so many stayed in service well beyond the life span of so many other vehicles, did their job faithfully, held up under duress, and even abuse.
