Is your quote fair?
A quote between $151 and $388 is inside the band where half of all Ford F-150 idler pulley replacements landed. Below it is not automatically a bargain (pulley only, belt reused); above it is not automatically gouging (complete tensioner assembly plus belt, tight access on transverse engines) — but both ends deserve a question.
What moves the price
Pulley or whole tensioner — the tensioner assembly costs more than a bare idler.
Belt — a new belt goes on almost every time — it's cheap insurance.
