I have an 03 sierra 4x4. All I have done is the Rough Country leveling kit. Well I found a service bulletin from alldata. This is especially true for noises seeming to come from the passengers front side. Truck was taken to a dealership. Using the J 43218 , crimp the clamp until the dimensions that are shown are obtained. The noise that mine is hard to explain.
I have contacted gm to no avail etc runaround. So I have the same problem. When the mechanic shop discovered that, they also discovered the master cylinder was completely dry, which caused damage to my front brakes. Sound seems to come from passenger side front. . I drove two other 04's and one 05 and they all did the same thing. Many refer to the front axels as half shafts.
Posted on Dec 29, 2008 How low is the mileage. If you have never done this before just get yourself a solid pinion spacer so you dont have to use those crappy crush sleeves when you put it back together so if you make a mistake your not running back to the store to get a new crush sleeve. Probably check the hub assembly as well but I doubt that is the issue. My problem is the transmission does not work properly. Others have discussed this on here before. I think I will take mine in to get it looked at by dealer in the next few days.
If you want them quiet he recommends new ring and pinion if there is damage to the old units. I was feeling excessive vibration and loud noise while under accelleration at speeds up to 60. Sorry, I can't remember what the part is called. Dealership's opinion was that the noise was coming from a dfective ring and pinion in the rear axle. Remove the clamp if applicable 4 at the transfer case 3 by prying up the exposed end of the clamp 4 with a flat-bladed tool. I'm new to the forum. I don't notice it on the dirt 'cause of trial noise levels.
Although the front differential should be checked for gearlube level, the trans fluid is not going into your differential. It was the opinion of the shop in bozeman j. Thanks I'd have to agree with bowtieguy. The Carrier in my differential had worn and needed replacement. These reverse cut Ring and Pinion gears will be noisy if not perfect.
Put it in drive and see if you can fear the noise. If you feel it in the steering, it has to be related to the front drive axle as you described. The condition may be caused by a loose spot weld that attaches the L-bracket from the left inner fender panel to the front bulkhead fig. I would suspect those bearings before the actual diff assembly, especially if the seals are leaking. . Thats where it sounds like the noise is coming from. If the propeller shaft is removed by using such means, the injection joints may fracture and lead to premature failure of the joint.
This is difficult to judge without hearing it myself. I believe one of the rear tires may have slipped and somehow the opposite disengaged and allowed it to continue backwards. Other than that, same purpose. But for the record these trucks have a pretty good differential. While many are the result of low fluid from leaks, a great number have also failed due to improper gear hardening during the manufacturing process.
I talked to two other owners who own nothing but Silverado's and they both told me it was normal. So dont let any dealer tell you it is normal, cause it aint. It's doesn't grind like metal on metal. Observe all published specifications and torque values and any measurements obtained prior to disassembly. This is on the street. Never done on dry pavement. Install the propeller shaft splines into the transfer case output shaft.
As far as noise goes, you are going to hear more on dry pavement from the extra bind. I have a Magnetic mount dial indicator and basic pullers is that enough to set up this front differential. New differential bearings, and quiet as a mouse. I will compare the noise to a quiet diesel motor, or a metal on metal sound like when a bearing is going out, or a distorted whistle, it hard to describe. These items include the following components: The propeller shafts The wheel drive shafts The pinion flanges The output shafts Assemble all of the components in the exact relationship to each other prior to removal. It was there when I test drove it and they agreed to fix it before I made an offer. I have had a number of clients with 4x4's swear they had problems with the front end.
