Well daily driver TTA 733 from Chicago has gone down!!
I was driving home from my parents and just started to get on it and then BANG and car had no go. I pushed it to the side and picked it up later with my trailer. Pulled the rear end out and look what I found, this was a stock nine bolt with a TA girdle. Not much help that thing was.

Is this something that can be repaired?? A new gear put in?? Or is it done??
I don't really wanna buy another rear end. So much $$$.
TTA 733 has 93k miles on it now. I am starting to believe Jason's theory that you can not daily drive a TTA, although I have been trying all this past year. This car runs 11.6 consistent, I guess that's too much for the stock 9 bolt.

Holy smokes. That thing was hurt bad before that roll on...Did you ever have any bad wheelhop incidents with this rear?
 
I can't see daily driving a TTA either. It must remain in the Toy catagory. Maybe as a weekend driver.

Good luck with the rearend Jarred!
 
Well, that stinks! Poor 733 :( My friend put a 9 inch into my old Camaro with the TTA Driveline when he bought it and that worked out well for him. I know you will get her back on the road soon and I have all the confidence about using mine as a daily driver if I needed too. You just can't beat on it. lol
 
Yeah lucky for me its winter here and I have nothing but time to get this figured out. I have put alot of miles on this car since I bought it. It had 78k and now 93.5k. So over 15k miles, thats about 26000 KM. I was driving this car to work all the time, I just figure I should drive it as much as I can cause:
1. Its so fun to drive
2. Summer here is not very long
3. Everything on this car works
4. I find it comfortable
5. Maggi can drive it if I need her to.

Jason yeah I did notice a bit of hop but only on left turns and only a few times. I should have opened the cover to inspect before she broke!.

Rob you have a memory of an elephant, I do have a spare rear end, I am just not sure of its condition at this time.

Mike I think you're right if I am going to daily drive it I can't be boosting past 20 all the time!!

This is Maggi's favorite car so I have to get her fixed up, just wondering what my options are. My buddy bought a used 12 bolt only to discover one of the axels was bent and his wheel wobbled as he drove. I am a bit shy of used parts, cause who sells a rear end unless theres something wrong?? I could check my spare rear end and see how good that one is but how long will that last??
 
If you don't want to go through this again a 9" currie limited slip works good for the money and it will take a beating... of course you know your stock spare will break sooner or later...
 
I would take the cover off the other diff and inspect ,If gears look good, you could change out the bearings for safe measures .Check the amount of torque to break one axle loose with the pinion flange locked to check the posi . Might as well use the diff if its good...
 
Put a new ring and pinion in it with all new bearings and turn down your boost Do not spin any limited slip or posi unit in a turn that and hole shots will tear it up all the time good luck keep driving it Bob
 
Pretty much look like mine did after blowing 4-5 teeth off at the track. I was beating on mine with a trans brake any were from 10-16 psi...pulled 5 consecutive 1.48 60ft before it went boom! I have a Curie 9" but wasn't ready to install yet so I picked up a set of 3.70 Nitro Gears from http://www.justdifferentials.com/index.php?main_page=product_info&cPath=22_31_76&products_id=2221 for $175 and put them in for now. With my 28" tires the 3.70 gears work great and actually put my speedo back almost perfect. Gear plus the install kit I was back on the road for under $400.

Put that spare 9 bolt in and tune that car back down to a 12.5 car and be happy.


It's my opinion that the 9 bolt can live for quit awhile at that power level but can't take the power and the 60' needed to run sub 12.1 passes.

Otherwise it's a grenade with the pin pulled.

Jarred,

I'm impressed with the number of miles you've put on that car since buying it from Mike...especially with the small amount of good weather you get in your area. For comparison I owned my car for 10 years and only put 17k on it in that time. Obviously it was not a DD for me and I don't think I could ever drive one that way. Heck, I had a 2013 Camaro for a rental and was growing tired of it after the 2nd day. Instead of bringing back memories of my younger years it made me feel like an old man. :wheelchair: I found myself helping my left leg squeeze in and if I hit a big bump my head would hit the roof! Good thing I had a dentist appointment at the end of the week because I thought I jarred a couple filling loose!

Good luck getting it back on the road, eh!
 
I think I may just put the spare 9 bolt in and leave it for the winter. I will make a decision on this later. What should I do with this broken rear end??

I have other projects planned that I want to start and complete. For sure ill have her ready for spring but that's not for 6-8 months. Lol
 
Hey Sweet, thanks Mike. How do I know if all I need is new gears, is there a way to test if the posi is damaged? or if there is damage to the housing??

Sorry for the rookie questions, I am not really a rear end guy ( more of a boob guy lol lol just kiddin)
 
Setting up the used gears could be hit or miss . Without a shim kit , you would be stuck using the shims that are in your housing now. Usually works ok but could have some gear noise on used gear set if not set up close to what it was at in the donator housing. Easiest would still be putting bearings in your other diff . Why was it replaced originally ?
 
I bought a strange S60 for my other TTA, so ended up with a spare. Now I have one rear for each car so no more kabooms allowed
 
If there were no bad noises from the old one , I would put it in and change the oil. Either way it just plain sucks to change break down parts, adding mods to go faster and more reliable is definitely more fun.
 
Yeah hoser I'd really like to put in a 12 bolt. I have one in my firehawk and its great. I just don't want to spend the time on a new rear end at this time as I have such little car time as it is lately and I want to do the interior of my TTA 366 and my corvette needs some work interior also. I also don't want to take up space with more car parts in the garage, I was going to get rid of the spare 9 bolt and Grumpy convinced me to keep it and now I am glad I did.
Inspection and oil change on the old rear is a good idea that is what I am going to do.

Well I put my spare rear end in and the car drives but makes a clunk ,.... clunk,....clunk,.... as I go forward slowly. I jacked the car up and put it in drive to observe from below. I still have not pulled the diff cover as I am lazy and was truly hoping it would "just work". I tried a second drive shaft just to rule out the u jonts and still the same. I do not believe the transmsission to be the source of the clunk as my guy looked at it and said it was not.

One reason I neglected to open the diff cover is I am having trouble sourcing a 9 bolt gasket. Has anyone tried using the red rtv sealer alone on the diff cover without a paper gasket? The one time I opened my other diff was to install the TA cover and it came with a gasket.

I found a wrecker who will line me up with a used 9 bolt (with me trading in my old one) for $1700. Sounds like a rip. I called strange and they will sell me an S60 all new for $2350. Maybe I can peice together one good 9 bolt out of my two broken ones?? I will have to open the cover and see whats in there I guess.
