I was listening under the hood today and noticed that one of the pulleys, maybe the tensioner or water pump is rather squeaky. I dont know if the bearing are just drying out or what is going on. Has this happened to anyone? What action should I take. I will be replacing the serpentine belt in just a few days and thought that would be a convenient time to look into thinks. Can I repack the bearings on these pulleys? Thanks. | ||

The bearings do dry out for the tensioner pulley. I think Atlantic British has a replacement/rebuild kit. Do a search here too. | ||

Andy, Please let us know how you get on and anything you learn along the way. I have the same issue, but it is almost impossible to tell where the sound is coming from, although it appears only sometimes at idle. Glyn | ||

I know I'm bad... but turning a large dial next to some numbers in the middle of the dash all the way to the right makes the squeek go away, very strange? | ||

Get a mechanics stethescope or a long screwdriver and put it against all possible part off of the S-Belt and you will hear which part is going bad. That way you know what you need. | ||

Did some more looking around, and listening with a nursing stethescope. Thats a loud engine! Anyhow, its either the idler pulley or tensioner. I had the tensioner off when I did the head gaskets and it looked fine. That was 20k ago, so maybe its the idler. Any hints on a repack job on this- my manual said nothing. Glyn, I hear ya, I'm no stranger to the red zone. | ||

I believe it is only rebuildable on the 94 thru 96 models....at least that is what I was told. | ||

I had the same problem, I just finished changing out my idler pulley. I got mine from DAP for $155 and it took a little time going in but the sound is gone. | ||

So, if it is my idler pulley making the noise, is that bad? I can only hear it with the hood up. | ||

I drove with mine squealing for 2 months but it only get louder.Im not sure what damage it could do but better safe than sorry. | ||

Probably the Rh idler pulley on a DII. The revised part number is PQR500060 and the new pulley is made of metal. It was a common enough problem that LR made a new part. Even if this is not bad it is a good idea to change this with the belt removal because it will be a future problem. | ||

My Aussie 98 LS 3.9 V8 idler squeeked. I removed, undid ciclip, pushed out bearing, went to bearing shop, bought new $4 bearing, preseed in using socket and vice, etc etc . No more squeek. Bazzle | ||

I too replaced just the bearing mentioned this past spring and eliminated the sound. About $5 at NAPA and 40 minutes or so... '97 D1 (Currently in ICU) | ||

Thanks for the advise, I think that I am going to try to salvage the pulley by replacing the bearings. I'll let you know how it goes. | ||

Andy just be aware that the circlip on the back of the pulley holding the bearing in is a bit tedious to get off - you'll need a very small screwdriver or two - unless you have the special circlip pliers... check this link http://www.discoweb.org/cgi-bin/discus/show.cgi?tpc=17&post=132763#POST132763 Also if you get the pulley warm (or room temp) and have kept the new bearing in a ziploc in the freezer for a few hours it will be much easier to press in (from LRO May '03 edition) Good Luck | ||

If you have the original pulley on a D2, replace it! even if the bearings hold up the pulley will chip, shred your serpentine belt and leave you stranded! ask me how I know... why LR put a plastic pulley on an 8,000 dollar engine I'll never know. |
