There is a tsb out for awhile on the squeaking over bumps cause by the spring insulator.
Suspension - Front Coil Spring Noise
Bulletin No.: 99-03-08-002B
Date: May 06, 2004
Front Suspension Coil Spring Noise (Install New Coil Spring Insulator)
1999-2004 Chevrolet Silverado 2WD 1500 Series
1999-2004 GMC Sierra 2WD 1500 Series Models
This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 99-03-08-002A (Section 03 - Suspension).
Some owners may comment on front suspension noise. The noise may be described as a "bong" or "clunk" noise. The noise may be more noticeable when driving slowly over bumps or backing the vehicle out of a driveway.
The front coil spring contacting the frame may cause this condition.
A new front coil spring insulator has been developed to correct this condition. Install a new insulator (1) to the top of both front coil springs. Refer to the Front Suspension subsection of the appropriate Silverado and Sierra Service Manual for coil spring removal/installation procedures.
This new insulator replaces any existing coil spring insulators. Remove and discard the existing insulator before installing the new insulator.

The insulators on our 2004 Silverado were replaced. We still have the noise. Now they
are replacing the steering gear box. Hopefully
that repair will take care of the front-end noise.

I guess! Winter just won't go away. My Dad and Sister are still up there. Although my Sister says she can't figure out why she's still there! Maple Festival coming up in just a few weeks. (1st weekend in April I think).
#4771 of 5688 HEATED MIRROR PROBLEMS
Mar 13, 2005 (6:24 pm)
HEY ALL........Anybody out there having problems with their heated mirrors on NBS full size GMs either cracking or not heating?
My left side one cracked, but still heats. The right side has no heat. The rear defrost works fine.
I have recently seen posts and pics at some of the snowplowing sites of mirror failures due to extended usage ...............
Mar 14, 2005 (4:23 pm)
My heated mirrors dont work well at all. Had once replaced under warrenty, the other quit not long after. I just gave up on them and left them. And mine were not from extended usage.
Mar 14, 2005 (5:53 pm)
You still have the 01?
My 01 didn't have the rear defrost or heated mirrors. This 04 with them is the cats axx up here in blizzard land when snowplowing !
I see quite a few posts of many failures on other sites. I wonder if there is a TSB out there about them?
GM Parts direct sells the replacement heated glass for under $30 each plus shipping.
Funny, I think its the shape of the glass thats the problem. The heated mirrors on my 96 and 03 Caddies were pretty square shaped and never had a problem.
Its under warranty anyhoo and I dump them every 30 months or so.
Snowplowing is tough on ANY truck!

I just had to replaced both on my '02'. Performance gradually deteriorated until they quit working altogether. About a hundred bucks worth at the dealer. What I can't figure is, what could possibly go wrong with such a simple devise?
Mar 19, 2005 (8:49 am)
What I see the most complaints about is the mirrors cracking.
My left mirror is cracked but heats.
My right mirror has no heat but is NOT cracked.
Hmmmm....Prob. another quality 3rd world made part.
Mar 19, 2005 (11:08 am)
Just a guess but, cracking mirrors may be characteristic of colder environs. Too much heat to that thin piece of glass at too cold a temp. Your right/left evidence seems to bear it out.
A word of advise to anyone removing a mirror for fault analysis: use a flat bladed tool with a THIN shaft. LOL, it won't take much stress.

Strange..........My 96 and 03 Caddies had/have heated mirrors and never a problem here in snowland.
Its either the shape of the mirror or a cheap part.
