schroed9 Posted December 31, 2013 Share Posted December 31, 2013 A couple of months ago developed intermittent whining. A couple of weeks ago turned constant after 30 mph but lessened with speed. This week has turned into a humming like when you put a card in the spoke of the wheel of your bike. Only occurs with depressing the accelerator. Took it to the shop, CV boot was torn so they replaced the axle, no change. Took to transmission and they think it is the deferential and say it is a $3500. The car is worth $2500. Is this the right diagnosis? Are there other options to fix or prolong the life of this car without this expensive fix? Please help! Greg Link to comment Share on other sites More sharing options...
lmdew Posted December 31, 2013 Share Posted December 31, 2013 Auto or Manual Trans? Check the gear lube in the manual trans or auto front diff. Might want to drain it and check for metal. Used Transmissions can be had for 400 or so. Link to comment Share on other sites More sharing options...
CNY_Dave Posted December 31, 2013 Share Posted December 31, 2013 If they changed an axle with a torn boot hoping the noise would go away (vs actually diagnosing the axle) they may not have sufficient skill to diagnose your problem. A whine when accelerating only is consistent with a bad differential. Link to comment Share on other sites More sharing options...
idosubaru Posted December 31, 2013 Share Posted December 31, 2013 Sounds like a bad front diff. if car is capable of many more reliable miles and in decent shape then it's worth fixing. Here's the best option and most commonly utilized by folks on this board: 1. $1,000 = $600 used transmission + $400 labor and new gear oil/transmission fluid. Those transmissions are robust and if one is in good condition when you buy it it's likely to last a very long time, change all the fluids immediately when it's installed and thereafter. Or: 2. $1,600 = $600 new ring and pinion and parts + $1,000 labor to install You'll need to find someone that's familiar with replacing a front diff though - a skilled shop or transmission shop. It requires some set up that many won't know or won't want to do. Most shops jump straight to rebuilds or replacements...not necessary, these transmissions are very reliable and a full rebuild is overkill. Just replace the transmission or the front diff if you can find a shop that knows how to do it. You can also source a used front differential but that's more effort than most people want to get into. There are numerous used transmissions in Utah for $500 - $600: 801-732-8400 1-888-832-2108 1-800-624-7062 1-801-252-0400 1-801-252-0400 expand your search to other neighboring states and maybe you'll find even cheaper: http://car-part.com/cgi-bin/search.cgi Link to comment Share on other sites More sharing options...
