#2581 of 3449 2000 Jimmy Front Tire? noise by jhighland Jul 31, 2006 (11:23 am)
I had new Michelin tires put on my 2000 Jimmy about a year ago and started noticing what I thought was loud tire noise. After three tire rotations and balancing and two front end alignment the noise was so loud I could barely hear my stereo so they ruled the tires defective and gave me brand new Michelin’s but the noise is still there? It starts at 5mph and increases from there. I put the car in neutral while going 40mph and the noise is still there. Apply a little pressure on the brakes, noise still there. The only time it goes down is when I turn to the left, but not the right. Jacked the back end up and started the engine and put it in gear at 40mph, no noise. Jacked up the front, did not pull the tires off but there appears to be no slack in the bearings   Help?

Sealed 1 piece hubs are most likely the reason - jack the front end up and spin them - if you hear or feel any grating/grinding thats it. 4wd need to jack up under the lower control arm so the CV axle will rotate so be careful and it requires a good floorjack.
#2583 of 3449 Front End Shimmy by jpmccr Aug 09, 2006 (4:04 am)
2001, Chevy Blazer - Ok, got the power issue resolved. Now the front end is shimmying (sp?) or shuddering - take your pick. Just did a front brake job. Once I got the old brakes off I checked the rotors and they were real smooth. No grooves at all. However once I got them all put back together and drove it, the front end shudders. Question: just because the rotors were smooth could they be warped enough to cause this? Didn't feel this with the old pads. I am thinking they need to be turned. Curious . . .

Replying to: jpmccr (Aug 09, 2006 4:04 am) Did it start with your brake job? Is it only when you stop? How many miles. 4wd? Replies to this message: jpmccr (Aug 10, 2006 3:40 am) repairdog (Aug 10, 2006 4:03 pm)

Replying to: jhighland (Jul 31, 2006 11:23 am) mine did the same thing I spun my wheels and did everything. My hub bearings was bad but u couldn't tell till u got them off and spun them.real easy to change need a 36 mm socket and a pipe(lol) and a large 3 jaw puller to pull the hub off of the shaft. you can them on ebay for $100 with shipping do both sides if one is worn the other isn't far behind.

Replying to: repairdog (Aug 09, 2006 12:14 pm) Sorry about that. 01 Chevy Blazer 4WD. As of this morning 86644. It started after I put on some new Bendix brake pads. It is a no brainer to install as to do the job, just remove the old ones after recessing the pistons, install the anti-rattle clips, pop the new ones in notches in the brake assembly, put some grease on the slide pin bolts, and reinstall the caliper assembly. I recess the pistons slowly using a C-clamp on the center of the old pad and push them back, nice and slow to make sure they go back even. The back brakes are the same way and I have had no problems with them. Easiest brakes I have ever changed (hate drum by the way). I am not real sure what changed except the pads. I am planning to replace the shocks as I noticed they look like they have never been replaced. I did buy this vehicle used. To me 5 years without changing the shocks seems to be a stretch, at least it is for me. Could this also be part of it? Replies to this message: repairdog (Aug 10, 2006 4:03 pm)
#2587 of 3449 Not working 4WD on Blazer S10 1998 by impalacab Aug 10, 2006 (5:13 am)
I got a Blazer S10 -98, with a non working 4WD. The transfer case works, the vacuum works and pulls the wire, the dash swithes works, the box and relays all work, everything seems to work except that the front wheels won´t drive. What could be wrong in the front axle? Is there some kind of "fork" that should activate the drive shaft or something taht could be broke or not in place?? Please help, Magnus, Sweden.

Replying to: jpmccr (Aug 10, 2006 3:40 am) Those Bilstins last along time and I have 4 Blazers all original shocks - over 150k. If the corners don't bounce they are probably OK - some have gone to reflex or sensatrac and that softens it up some but bet thats not the vibration cause.

Replying to: impalacab (Aug 10, 2006 5:13 am) Yes there is and the cable pulls it in and then that 2 wire electrical connector is to a sensor that tells the 4wd computer or TCCM that its engaged. You should hear the coupler engage and disengage as vacuum is applied and removed.

Lost all power and engine shut down,then i noticed there was no oil pressure,checked oil level and was full .Could the oil pump make you loose power and shutdown if it goes out?And can it go out all of a sudden?Or can it jumping time cause this?
