Just want to thank everybody who gave me advice on how to get rid of my engine squeel or whirring noise on my 96 LX450. Relaced all belts with OEM parts (got rid of old ''notched'' belts) and truck runs as quiet as new!!!!!!!!! Thanks alot again from your ''Canadian hoser'' friend !!!! Tim p.s. - replaced all my shocks about a month ago - was wondering if I should repace my springs as well?- I've got 120,000 miles on my unit.
