    Unhappy Noise/rattling when doing rapid accelerating from full stop

    A noise comparable to a mud guard hitting the tire can be heard when doing rapid acceleration from stop. A few month back I change all 4 tires in my 2004 SRX V8 and they did something with the alignment and don't know if this was the cause of the problem or do I need to change any part of the suspension assembly. Have anyone experience something similar?

    Sounds like you have the same problem as I do. It might be the transfer case chain is worn down and needs to be replaced, or the transfer case itself may be broken.

    It only happens on hard acceleration from stop but once you reach 30kph and do hard acceleration then there is no problem. also I only got 109km on it and do we need to change the chain every 100k? how much it cost you to repair?

    Re: Noise/rattling when doing rapid accelerating from full stop

    I seem to recall there being a "known issue" with some of the transfer cases for 04 and i think some or all of 05 model SRX4.
    I believe there was a better chain offered after a while to replace the old one.

    And better yet check out this thread:

    Here is an image from that thread showing the stretched chain side by side with the new one:

    I wonder if someone can count all the different transfer case threads, there's got to be over 200 about 04 V8's with this. I started one like 4 years ago. 1700 for AAMCO to replace with a reconditioned unit. Started happening to me at 80k miles, by the time i took it in at 120k the damage was really bad

    Your problem doesn't seem as bad, mine pops at any medium-hard acceleration. Even at 70 if I accelerate to 80 it still pops. Already bought a new chain as the old one is destroyed and plan on replacing it. The chain cost us $145. Also while idle the car seems to vibrate, after further investigation we found that one of engine mounts was broken completely. That's what you get with a 9 yr old used car I guess.

    I had a heat shield rattle on the passenger exhaust pipe was quite annoying and according to the dealer somewhat common. They used a hose clamp to resolve it. It's near the bottom front left of the passenger seat.
    So something else you may want to check out.

    Re: Noise/rattling when doing rapid accelerating from full stop

    I already bought a TRANSFER CASE CHAIN CADILLAC SRX BW4476 BW4479 HV-095 2004 for $135 and another $20 for forwarding to Qatar. Hopefully mechanics here will not charge me a lot for the replacement. I'll give update once this fix has been done. Thanks!
