steering clunk

[davecross1]

Hi guys! There is a new kit on ebay that bolts on and eliminates the clunking in the steering on the 02-08 chevys. It just bolts on and only takes about 10 min! You can look it up by typing in CHEVY STEERING CLUNK REPAIR>

this issue is resolved by lubing the ISS....much cheaper ....also I did this back in 2001 still no clunking...

The shafts I am covering dont go back to 01, but thanks for the input.

I saw somewhere on here where it was called a scam, its not a scam, just a red blooded american trying to sell a good product. And to be specific on what it is-gives it away but here you go. Its a heavy duty split steering collar that has been modified by welding contact points on the I.D. to slightly distort the shafts roundness enough to eliminate the play in the splines, but not so much as to damage the shaft. Hope this clears up any questions, Thanks.

the 2001-2006 should be the same part ..for the ISS....................

2007 on up not sure ...

but anyway the TSB on these is to lube it..I agree with this as the solution////unless it was beaten.......

cheap easy fix on these 2001-2006 vehicles.

Not to be a troll but the latest TSB has us replacing the I-shafts with a updated design. I have had 0 comebacks with the latest redesign, though thank God I think we have all of them takin care of in my area.

omg, they have never ever fixed the darn steering shafts? what a travesty

anyhow. permanent fix is to install a zerk into the flattened piece of ISS, right above the 15mm bolt, then pump it with quality lube. takes about 15 minutes to install and costs few bucks, unless you have to buy extra tools for it.

The only issue i can see is if the splines are worn badly, it may not cure it or may have to be maintained more frequently.

First, open the hood and turn the steering so the connecting bolt (about 12 inches from the firewall) is positioned with the head pionted up.
You will need a hammer, centerpunch, 1/8" & 7/32" drillbits, drill, a 1/4x20 thread tap and handle, a grease fitting with 1/4" thread and a grease gun.
I used a multipurpose chassis grease with 40% Molybendum content.

First centerpunch then drill a 1/8" pilot hole at the top of the flat above the bolt head , then open the hole with the 7/32" drill bit as shown.



Next using the 1/4" tap, cut a thread in the hole(as shown below) but only cut about half way up the tapered tip of the tap so when incerting the nipple it will be very tight. It is ok if u cut a full thread, the nipple may not tighten as securely.




Next incert and tighten the grease nipple in the hole, Be careful not to over tighten.
It should look like below.





Last step, pump atleast 30- 40 shots of grease into the fitting, then drive it 50 miles or so and pay attention to weather the noise comes back. If so pump another 30 shots of grease into the column.
This should eliminate the noise and give the steering a bit smoother feel.
You may add a few shots of grease to the column when and if the noise returns , to maintain lubrication in the spline.
Notes: It will take about 100 shots of grease or 3/4 of a tube and the grease will start coming out of the bottom of the column at the steering box end. I may sujest to disconnect the column at the location shown in the pictures and plug the upper portion below the grease nipple, then pump in the grease. It will require less grease and will put a bit of grease pressure in the tube which will prolong the time between maintenancing the spline but is not nessesary. I packed a rag in the bottom of the column when the grease started to come out and put pressure on the rag with a small prybar to create some pressure but it was not nessesary to complete the modification.

UPDATE: JUST AT THE TIME I WAS FINISHED THIS MOD, ONE OF THE GUYS I WORK WITH TOLD ME THAT HE DID THIS MOD TO HIS 03 gmc TRUCK 5 MONTHS EARLIER. HE WENT FOR ONE RIDE, REGREASED AND HAS NOT HAD TO TOUCH IT SINCE. HAS OVER 6000 MILES SINCE THEN AND IT IS STILL QUIET.

Try it at own risk, if u are not confident that you can complete this task, get a shop to do it for you.
Post your results and updates for all to see, good or bad.
Thanks and good luck, hope this works for you as well.

shaft with a Steering Column Intermediate Shaft Lubrication Kit, P/N 26098419.
Follow the service procedure below.
Set the front wheels in the straight-ahead position.
Set the steering wheel in the LOCK position.



From inside the vehicle, remove the upper bolt from the upper intermediate
steering shaft (1) to the steering column connection.



From under the hood, remove the lower bolt that connects the upper
intermediate shaft to the steering gear coupling shaft.
Remove the upper intermediate steering shaft assembly.
From inside the vehicle, slide the shaft down and off the steering column
shaft.
From under the hood, slide the shaft towards the dash in order to disengage
the shaft from the steering gear coupling shaft.
From inside the vehicle, slide the upper intermediate shaft through the dash
boot seal and remove the shaft from the vehicle.




Remove the spacer clip from the end of the intermediate shaft with a pair of
needle nose pliers.
Fully extend the shaft by pulling the two shafts apart.



Apply the syringe of grease supplied in the Steering Column Intermediate Shaft
Lubrication Kit, P/N 26098419, into the open end of the shaft. Direct the
syringe tip as deep as possible into the shaft and dispense the full content
of the syringe.



Insert the plug supplied in the Steering Column Intermediate Shaft Lubrication
Kit into the open end of the shaft and finger tighten the wing nut.



Place the plugged end of the shaft on a hard surface and apply pressure to

Inspect the shaft for a minimum of 13 mm (1/2 in) of grease on the shaft
splines.
Repeat steps 10-12 if less than 13 mm (1/2 in) of grease is on shaft splines.
Clean the excess grease off of the shaft splines and around the shaft opening.




Carefully spread apart the spacer clip with a pair of pliers.



Reinstall the spacer clip into the open end of the shaft.



Align the spacer clip with the stakes in the shaft.
Reinstall the upper intermediate steering shaft through the dash boot seal and
slide the lower end into the steering gear coupling shaft.

No that is a revision A TSB the one I posted is N. It has been through so many revisions. They want the I-shaft replaced with the P/N I posted above now and NOT lubricated

ya I know that was "A" tsb on that number..like I stated GM has made about 12 revisions with this issue... the latest is the N tsb with that number.

as all can see this effects more than the 2002 vehicles that you stated in your earlier post ...

so for a decade GM did nothing about the poor fitting ISS !

now they come out with a part that fits correctly..

So why did you copy and paste the old (first) TSB? Are you using SI or something else?
Reread my post. I never said 2002. It applies to 2002-2006 and some 2007's.
