I've been noticed that the car has a loud clicking noise when I accelerate, and it is more noticeable at lower speeds due to less wind noise. Anyone notice this as well?

If it is more noticeable during turns I would guess CV joints, check your CV boots and see if they are torn or have grease covering the area.

Is your AC on during these probs you have quoted, if it is, then it is the Denso Damper (For Airmix) Servo Sub-Assy which is rite behind the cluster which make this click noise, This normally is high when the cabin temp is mid range, the servo assy fins with motor does not move and the gear tooth keep slipping and make this click noise till the cabin temperature cooling matches the set temperature by the ecm.
Solution, remove the cluster and remove the unit and the gear tooth of the servo assy needs mild cleaning with is Isoprene Alcohol and mild grease.
Now this click noise I had this and this is exactly what i did.

Wanted to see if this is simiar to what is occurring with my 02 RX 300. While accelerating to highway speeds there will be a clicking noise coming from the passenger side front end. Once up to speed and normal speed there is no clicking.

There is a TSB to Windshield Upper or the lower end Tick noise for all Lexus Model Model until 2008 included. If that is you what you conclude to your model.

Send me you email address those who are under warranty can have this done via the dealer. the TSB will be emailed to you.
Those who dont sad luck will need to replace the retainers and it is long job. Method can be sent to you email address if you are interested in doing at home privately. Or for that matter some known garage who dont rip you off.

This would do it regardless of acceleration.

I've seen some cracked exhaust manifolds. They click under load.

Pay a technician some diagnostic time and they'll likely sort the cause out quickly. They internet can only help so much.
