how do i know if i need the TSB?

I am having trouble understanding the TSB thing. How do i know i need it? I am getting an 09 of road 4x4 crew cab. I know i can look and see if i have 4 springs but i guess sometimes three are ok. Anyway a simple laymans term answer would be great. I will probably not be able to get them to fix it if i do need it but i think i will threaten to not take delivery. there are 4 other dealers in the area. anyway thanks for the info in advance.

 

I just picked up my '09 on Monday. Tonight, I went out with a flashlight and looked behind the left wheel. On top of the springs, there was a part number in big white letters. I checked that part number against the service bulletin and it indicates that it's a defective part. I didn't bother checking any of the other parts.

I'm going to take mine (with a copy of the TSB) to the dealership this weekend to get it replaced.

 

Will do.

 

let me know how it goes i will try to make them fix it before i pay for it. so the part number on the truck was the previous part number from the tsb 48210-04550?
thanks

 

I just checked the left side, but the part number I had was 48220-04190 G LH

 

this is from the lemon law tsb post i thought i remembered something about letters.

 

thats good info thanks

 

I just looked at the new TSB. It list the previous part number for the LH spring as 48220-04190 and then the replacement part number. I went and checked mine, and it is 48220-04190-G. The TSB does not specify F or G at the end of the part number. I think I will have mine checked just for peace of mind.

 

yea sounds like a good idea let me know what you find out

 

I did extensive research on TW before getting mine. In a nutshell some say the 'g' springs are OK. Others say if it is not the '4' pack get it done. I think your right that the TSB doesn't specify a letter.

I had the 'f' springs and got mine done. I recommend to get it done no matter what the letter is. I have not found one person on here that has regretted getting the rear spring TSB. They may be here but I haven't seen it.

You can also search TW and find many techniques to help guide you on the best ways to get the TSB done. The 09 isn't on the TSB yet so you will need to get brushed up on what others have done.

 

I just went by the dealer:

ME: "I bottomed out on a bump with a few bags of sand in the back. Then, after a little research..."
HIM: "(interrupting me...) You found a TSB on it?"
ME: "Yep."
HIM: "Yeah, I just did the first one last week. I'll order the parts for you. When do you want to bring it in? Let me get some numbers off your truck."

Never even checked any of the parts for part number eligibility or anything.

Also, he mentioned that the TSB included something about the front shocks/coils/something on the front... Does it? I thought it was just the springs in the back...

 

The TRD only gets the rear springs changed.

 

Set up for the 20th for the TSB, service guy was emphatic about how stiff my suspension would be after it is done. I hope I am not disappointed that I had it done.

 

Yeah, the service manger tried to tell me the springs would be thinner and the truck would set lower and the ride would be mushier. Boy was he wrong on all counts. It still just rides like a truck, but now will haul like a truck! They just don't want to have anyone come back. Because if you go back afterwards then guess what...sorry bout yer luck! You pay for it the second time.
But don't worry, I still haven't heard of anyone regretting it.
And I'm very glad I did mine!!

 

You are right phantom. And thanks..can't say that anymore
Just haven't seen any on TW I guess. Probably there somewhere though.

Squeek is usually due to improper install. My new ones had super thick grease in several places between leaves. Maybe it wasn't on theirs. New ones have had same problem a few times.

Some on TN thread were made happy when Toyota paid for Timbrens to correct problem. This tends to make me suspicious of a possible known material defect, or another problem covered up. This does not seem to be common practice, and definately isn't on the TSB.

#24 wasn't happy ,but the tongue weight might have been pushing it with a 16' tandem trailer and possible other cargo. He didn't say if truck or trailer was full or empty, and of course we all drive at different speeds over bumps. There is a limit to the TSB springs too.
Bottom line the TSB is personal preference. Most call the original 3 pack a gentlemans ride, while others that have the 'G' springs have loaded them down and been fine.

Maybe should poll for TSB Rear Spring satisfaction?!?!?! That could be interesting.

 

well said....
