I have owned a 2003 xl7 for about 1 year now. (5 speed manual) When I purchased the car, there was a strong singing noise in 5th gear at around 90 - 100 k/hr. The car has been back to the workshop 3 times now with attempts to fix this problem. The last attempt was to replace both 5th gear cogs. This was still not successful. The noise is still there although it is much quieter, but the singing now starts at about 85 k/hr through to about 105 k/hr. Has anyone else had any problems with the xl7 5 speed manual gearbox? Every thing else about the car seems fine. One thing to note - when I picked up the car from the workshop after the last attempt, the service agent said they had considerable difficulty getting a cog off of the shaft??? Dont know if this could be part of the problem.

Thanks

Jim

whining noise

has any one found a fix or cause of problem as seems no one has had a fix dealer said it was normal on this model and trying to fix may cause problem to increase or change to a different km range ,maybe better to live with from other posts on this forum:eek:

I've been reading this and the similair post on the whine / noise problems. It SOUNDED like typical ring and pinion noise to me at 1st, but after several dif replacements by that other fellow, and now this post, it has to be the transmissions.

If out of warranty or you are at your last resort on repair attempts, try some Redline synthetic gear oil. It has been known to quiet gearing and improve shift performance as well. I was sceptical at 1st, but it does work well in my 300ZX and Zuki.

Available at some parts stores and on-line at places like Summit and...

whine

thanks max my car is the 5 speed auto and is still under warranty which diff gear replacemnt will be done under but am now a little hesitant to have it done in that it may worsen the problem,but then again have plenty of warranty left!!! so if it came to it would go further with the issue with suzuki

if the whine is from the rear of the vehicle, try replacing the wheel bearings...hopefully the diff fluid was replaced when it was recommended by Suzuki...the original factory fluid is a break in fluid that needs to be replaced at about 7,500 miles...if it's not, it could lead to premature wear of the diff which would also cause noise

whine noise finally fixed

after taking the Suzuki rep out for a drive he finally decided that yes there is a problem which is known to Suzuki!!! so he then organised to have new diff gears ,bearing etc installed by a Differential rebuild specialist NOT the dealership . on enquiry they "blueprinted the diff" spending time lapping the gears and ensuring correct clearances are followed. one thing i did find out is the standard rear diff is not a close tolerance unit produced by suzuki!!!!! and after picking the car up was surprised to find the Whining noise has dissappeared. now a happy owner and do commend the Suzuki rep on thinking outside the circle.:rolleyes:

all it was was not proper maintenance. Like said before fluid HAS to be changed at 7500 miles. Or this happens.
in fact I wil be willing to bet then its all bs. The dealer did the swap themselves and told you that.. Suzuki Coperate will not pay warranty $$ to another place to 'blueprint' ther rear. Sorry don't believe it..

hate to disappoint you

I actually went down to the Diff rebulder and saw for myself and personally spoke to the mechanics so to satisfy myself that job was done as asked , you seem a bit skeptical !! so was I but DID see it all in person and as i said THIS is a known problem on this model XL7 which was verbally given to me AND not in writing for legal reasons.
anyway job down and no whine!!!;) :huh:

i had the same whine and it was the diff. and i had to replace because i did not change the gear oil. i was able to get 110k miles on not changing the gear oil, which i wasnt told, but consequence is a new rear diff. and no noise. i will change every 7500 miles now and also dont forget to do transfer oil. i do it all at once every 7500 just to be safe than sorry..
