    I have a 2003 Lesabre w/13,000 miles on it. The cruise control will hold for 45 minutes or so, then drop off 3 MPH or so and hold at the new, slower speed. Does not happen every time. Thanks.

    It's under warranty at 13K. Let the dealer diagnose the problem.
    There's a Buick discussion and a couple of Bonneville discussions here.

    Obviously.....that is where I'm headed. Was just looking for opinions beforehand. Thanks.

    Sometimes the tach used in the instrument cluster has a jumper option for 4cyl or 6cyl. I have seen where the jumper would be loose, or just not making good contact, and the tach would get really flakey, falling to below 0 or jumping to 4000rpm on idle.

    One thing that sometimes will prove this is to firmly hit the dash above the tach with you hand and watch for the malfunction.

    Saw this on a 79 Olds Calais and drove folks nuts until the problem was found. Soldered the jumper down and the problem never came back.

    My 1998 SL2 has a loud spring {twang} noise comming from the rear of the car . I looked up all the SB and it seems that the strut springs rotate and make contact and rub . I turned the springs put teflon spacers between them and they still make noise when I go over a bump. The only time it stops is when it rains.Could it be a sway bar or something else?? Mike
  • Hi, I really don't drive very often and I find my battery always dying after not driving for a while, I was wondering if there was any device or some way to prevent this from happening?

    You say the noise stops when it rains? Many years ago we used to spray brake fluid on all under car rubber bushes and fittings to lubricate them and stop them from squeaking. Maybe a few shots of brake fluid from a squeeze bottle with a nozzle will help? Take care not to get the brake fluid on your car body paint though.

    Whenever I start my Trooper, there is a LOUD squealing noise, just like a slipping belt, somewhere in the engine, for about 15-20 seconds. The it goes away.
    I've been told that its the timing belt, but I'm not sure.
    Anyone else have this experience?

    If your car's parked outside, there are solar powered trickle chargers available which sit on the dash and plug into the cigarette lighter socket.

    Which engine? Serpentine belt or multiple V belts?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,404
    nah, timing belts only slip once and then you're done!

    Could be drive belts or idler pulley or bad alternator bearing.

    One quick thing you can do is spray just a little WD-40 on the belts before you start it up cold and see (hear) what happens. Or even rub a bar of soap on the belts inner side, with the engine off of course--LOL!

    I have 1978 Mercedes Benz the motor still runs when I shut off the engine. Could you please tell what the problem might be.
  • Any idea why I am experiencing excessive wear on front wheel bearings ? I have gone through 3 sets of wheel bearings (hub assembly) since my car reached 100k and they are averaging 4-5k of life per replacement. Front end parts seem to be fine, I've also replaced all brake parts as process of elimination i.e. calipers, rotors, pads, even replaced rims and tires after first two hub assy set replacement so there seems to be nothing left to attribute the premature expiration to. I dont drive that hard on them so that should'nt be an issue. The only thing I can figure is perhaps the hub assy I am purchasing at a local discount auto store (rhymes with "worries") are poor quality and arent lasting as long as OEM's might. The "specialist" at the store assures me that they have received no reports of others having problems with them and there have been no recalls on the part but I'm growing weary of returing them (under warranty) and having to keep replacing them. I get the feeling they think I'm doing something fishy to cause them to wear down with only 5000 miles on them and I'm getting the cold shoulder with each return visit. Please help !!!!

    i have replaced the hub bearings on my ford.i believe i purchased them from the same chain as you did.i have had no problems.i am wondering if you are properly tightening the hub nut to specs with a torque wrench.
  • 37453745 Posts: 152
    The only thing left that might be causing excessive wear of the hub bearings could be rims that are not putting the weight of the car directly under the bearing. A situation like this can be caused by spacers fitted between the hub and rim or, replacement rims that are offset with reference to the OEM rims. Make sure your replacement rims have the same depth as the OEM rims measured from the inside of the rim to the mounting surface that goes onto the hub.

    Is this Benz a diesel or gas engine?


  • Thanks guys, I will pay closer attention to the torque applied this time but almost certain it was correct ... excuse my ignorance but how would incorrect torque cause them to fail prematurely ?

    ... the rims I spoke of, ARE IN FACT OEM's ... replaced them with identical factory insatlled originals and since the problems occurred before replacement (twice) and continue after they were installed, I'm pretty confident this isn't the problem ... where do I send the gratuitous pizza and beer for all of the money you guys have saved me in the past? I'm about to buy a 95 Cutlass Supreme Convertible so Im sure I will be asking for more help when the needs arise.
